Twin Slot Shelving

Twin Slot Shelving, a UK specialist in twin slot storage systems

Twin Slot Shelving is a shelving specialist company set up and run by Charles Watson (Ironmongers) Ltd. Its stated aim is to give the UK a high-quality source of a wide range of shelving systems, covering shelving uprights, bookends and shelves, alongside full long span shelving as a rapid racking solution. The company presents itself as the UK's leading source of uprights, brackets, bookends and shelves, a claim that reflects its own positioning rather than an independent ranking.

The range is organised around the twin slot system, in which uprights carry "U" slots into which brackets slide. Once the uprights are fixed, shelves can be repositioned or changed without reworking the wall, and any shelf from wood to metal can be fitted. The company describes this flexibility as suitable for offices, schools, homes and hospitals.

Components and finishes available

The catalogue is built from the individual parts of a shelving installation rather than complete kits alone. It is grouped into uprights, brackets, bookends, shelves, shelf stiffeners and shelf ends, with a separate section for other shelving and other brackets.

• Uprights in white, black, brown, matt silver and polished chrome.
• Brackets in white, black, brown, matt silver and polished chrome, plus stainless steel and heavy duty versions.
• Bookends in white, black, brown, matt silver and polished chrome.
• Shelves in white and stainless steel, with shelf stiffeners and shelf ends.
• Other brackets, including fluted angle brackets and London shelf brackets.

Beyond twin slot components, the shop lists ProFrame square tubing, steel tubing in round and square sections, and long span shelving units. Finishes across the range include white, black, brown, matt silver, polished chrome and stainless steel.

Fixings and installation accessories

A dedicated fixings section supplies the parts needed to mount a system: screws, drill bits, Uno plugs, spring toggles, plasterboard hollow wall fixings, GripIt and Rigifix. The company frames this as giving customers everything required to install a new shelving system in one place.

The listings show individual components in specific sizes and finishes.

Delivery and support

The site advertises a flat-rate delivery charge of £15 for mainland UK and states that expert advice is available online. It also publishes blogs and guides, including an installation walkthrough for twin slot shelving in a home or garage and an explanation of why the system might be chosen over other shelving types.
