The SDTSB-40 offers total extension front and rear. This is made possible by an internal rocker device which releases each beam in sequence. Ideal for thru-truck drawers where access from either side may be limited. This is a heavy load/duty full extension telescopic slide (84-245 kg/pair) suitable for a wide range of applications. At 550mm 1 pair has a full extension load capacity of 245 kg.

Constructed from milled stainless steel 316L sections, with machined ball tracks for accuracy, it has excellent levels of shock and vibration resistance. Accordingly, the product is well suited to supporting military truck drawers, offshore stowage and ship-borne seating. The slide beams, cages and ball bearings are manufactured from austenitic grade 316L (1.4404). End stop bolts and retaining pins are austenitic grade 304 (1.4301), completing the corrosion protection, There is the bespoke option to manufacture an all 316L product on higher production volumes.

Due to the extreme strength of the mobile 'I' beam, this slide is robust to applied loads when in the extended position making it an excellent choice for dynamic applications. Unlike many other slides manufactured from rolled 'C' sections. There are no plastic parts in the manufacture of this range, making it ideal for extreme temperature use. Grade 316L is an austenitic stainless steel with a very low electro-magnetic signature, so ideal for defence applications.

SDTSB slides on accurate robotic pick & place or high speed shuttles require factory adaptation and customer in situ testing, prior to committing to production.  The beams are precision ground for accuracy and ball cages laser cut. However, constant low force usage will lead to some bearing migration without an operator to realign about every 2,000 cycles. The slides are limited to operational speeds of <0.3m/s. We are starting a laser hardening programme for the ball races, to launch in Jan 2024. This will increase the hardness to 62hrc, operational speeds to 0.7m/s and reduce the operational forces to traverse. This will make the slide ideal for robotic usage with a substantial economy over expensive induction hardened beams.

The SDTSB-40 drawer slide may also be fitted in the minor axis (flat). However, the load capacity will be reduced by 60-80% of the stated loading. A single SDTSB-40 weighs 5.65 kg per metre.

Ground, marine and air defence vehicle applications such as equipment stowage, mountings for weapon systems and racks for electronic systems

Ship Borne

Applications can range from slide based storage systems, lockers and furniture, through rack mounted electronic components, and onto operational and weapon systems requiring linear movement. If required products manufactured from high grade stainless steel can be supplied offering highest levels of corrosion resistance and low magnetic signatures.


Slides and bespoke sub-assemblies for mounting electronic and other equipment including weapon components on vehicles ranging from lightly armoured personnel vehicles (radio and other electronic components) through to battlefield tanks (internal storage, ammunition handling, slide-out generators and workstations).


Equipment stowage components and systems as installed on fire engines

Slide Drawers

Solid section steel slides lengths from 300mm to 2,000mm for pull-out equipment drawers. Extensions from 50% to 150% of closed length can be supplied, in addition slide systems that offer sequential dual extension with bi-directional travel allowing the drawer to extened from either side of the vehicle. This enables rescue crews to access vital equipment quickly and safely, regardless of the vehicle's orientation to the emergency scene.


Our range of reinforced heavy duty steel slides fitted with additional ball tracks and reinforceing ball bearings are ideally suited for use in some of the more unique applications. Together with a range of slides designed using a rigid "I" beam construction our products offer execelent performance under conditions that may exert high direct and tortional loadings as experienced in such applications as pull-out equipment boards and vertical shelves.


Following extensive testing on selected models our slides are used by the U.K.'s leading producers of complete equipment carriers. These complete tray systems are ready for quick installation, including bespoke mountings for specialist equipment such as auxilliary pumps, tools, hoses and rescue equipment.

Lock-in and lock-out mechanisms facilitate quick and safe operation of the equipment carrier, as well as hold the fully-loaded drawer securely in position when the vehicle is in motion or at the scene.

Food Truck - Mobile Catering

Whether you have a full side trailer extension to build or a small pull out coffee machine tray from the back of a Vespa Ape, we have the right slide for you. From specialised mobile military deployment catering units to market trader applications, we have the knowledge to make it happen.

We are a privately-owned company, established over 30 years and our slides and tool mounts cover every possible application within the catering and hospitality industry.

Our speciality are bespoke telescopic slides suited to catering trailers and full van conversions.

If you require a light load slide we suggest using our standard rolled steel slides covered in this section, for larger full vehicle conversions up to 2000kg we recommend our cold drawn steel section I beam heavy duty slides. The rigidity and strength of the material used in the manufacture, without use of plastic components, make the slides appropriate for heavy duty usage which demand resistance to shock and vibration.

In addition to telescopic slides project we supply auxiliary equipment to fix pipes or other tools.

Our Fulterer range of slides comply with NSF food grade specifications to allow for installation of our drawer slide in direct contact with food.

Motor Manufacturing Plant

Telescopic Slide and Linear Rail components for lineside delivery and component handling systems

Automated Production Lines

Linear movement components and telescopic slides for use on repetition-intensive automated production lines. Components require a high resistance to localised wear patterns, uniform operating loads and designs capable of working at fast speeds with high accelerations.

Manually Operated

Linear rail and telescopic slide products for component delivery and handling at line-sideassembly stations.

The breadth of our product range gives you an unparalleled advantage when engineering solutions for delivery systems that have to accommodate large irregular shaped components or sub assemblies within space restricted line-side delivery stillages.

Correct selection and specification of the slide system will ensure maximisation of the space inside the delivery stillage and production efficiency while accommodating the natural variations of manual handling present in a time sensitive assembly environment.

RV & Motorhome

Special & Commercial Vehicles

Our telescopic slides and tool mounts cover even the most demanding project for commercial vehicles. Smaller, lighter duty rolled steel or solid section slides from our General Devices range will suit a keyboard tray or a display screen, whereas cold drawn steel section slides will fit requirements for full vehicle extension such as mobile broadcast vehicles carrying several 1000kg’s.

With over 30 years of experience, we are more experienced than any other supplier and manufacturer to be able to advise of suitable and performing products.

Sliding Systems are an approved supplier for many prestigious and well-regarded manufacturers both in the United Kingdom and abroad.

With our flexible production facilities, we can accommodate any project and are pleased to assist with special requests whenever possible. Applications involving shock and vibration call for heavy duty, cold drawn steel section slides which we are also able to supply in 316L marine grade stainless steel. If weight or corrosion resistance are parameters that are important we suggest Aluminium T6 section slides, available in load capacities up to 330kg.

Outdoor applications can be fixed in place with specialist marine grade 316L hooks, which safely hold tool boxes or vehicle covers in place.

Response Vehicles

Roadside assistance and other categories of vehicle that need to stow and provide easy access to equipment can be enhanced through appropriate use of telescopic drawer slide and linear rail systems.

The twin requirements of operator safety and operational effectiveness are of paramount importance. GSF's ability to select and adapt from an unrivalled base product range, and its ability to assist with the design of bespoke and space-saving drawer systems enable us to make a significant contribution to your own product design.

Yachting - Marine - Non Corrosive

The need for storage is not confined to land structures, every seaworthy structure requires a multitude of pull outs or heavy-duty generator tray. We can offer the widest range of stainless steel 316L telescopic slides and non- corrosive tool mounts.

For interior fittings we suggest 304 stainless steel slides, larger heavy-duty applications are covered with our specialist bottom mount General Devices D1050/D1054 slide. The latter allows the user to look a generator tray in the opened and closed position. Bottom mount slides are useful for applications where space is limited thus a traditional drawer slide installation is not suitable. The poxy coating offers some corrosion resistance but achieve full corrosion resistance, we suggest stainless steel 316L which can be supplied upon customer request.

Our full professional range DTS is now available in marine grade stainless steel 316L which includes the end stops and ball cages. With low profiles starting from 40mm up to profile height and lengths up to 2000mm we are confident to be able to supply a complete range.

As a distributor of the prestigious yacht and boating equipment manufacturer Viadana SRL, we are also able to support your yachting project with their full chandlery range.
