Rectangular Tubular Legs

Fittings & End Caps for Rectangular Tubular Legs

Finish and protect hollow box section furniture with our commercial-grade range of rectangular tube inserts and external rectangular ferrules. Engineered for rectangular hollow sections (RHS), our durable end caps deliver a clean professional finish, prevent internal frame corrosion, dampen dragging noise, and protect floors from sharp cut-metal edges.

Robust Performance for Desks, Frames & Fabrication

Our rectangular fittings are widely used across office desking systems, industrial workbenches, commercial table frames, school furniture, and structural metal fabrication. Moulded from high-grade polyethylene and resilient rubber compounds to withstand heavy static loads and constant commercial use without cracking.

Essential Fixings for Rectangular Box Sections

Choose the correct fitting profile for your rectangular frames:

  • Internal Ribbed Inserts: Push-fit rectangular end plugs featuring horizontal flexible fins that compress tightly inside hollow steel and aluminium tubing.
  • External Rectangular Ferrules: Push-on flexible end caps that fit over the outside edge of rectangular legs, providing full outer rim protection.
  • Clean Flush Finishing: Designed to sit completely flush with the outer tube walls for a neat, snag-free base.
  • Impact & Moisture Protection: Seals open tube ends to prevent dirt ingress, water collection, and frame rust.

Outer Profile Fitment

Our collection covers a comprehensive range of standard metric and imperial rectangular section sizes. Sizing is based on measuring the external dimensions (width × length) of your metal tube to ensure an exact fit.

Multi-Gauge Wall Thickness Compatibility

Our internal rectangular inserts feature flexible ribbed fins designed to adapt to a wide variety of metal wall gauges, providing a tight friction grip that prevents loosening or dropping out over time.

Durable Colours & Finishes

Available in industry-standard black, white, and natural grey heavy-duty moulding polymers to match powder-coated, chrome, or bare metal frames.

Pack Sizes for Maintenance & Production

Supplied in compact quantities for repair jobs, trade contractor packs for facilities maintenance, and bulk wholesale quantities for high-volume commercial fit-outs and furniture manufacturers.
