Rectangular Unistrut End Caps

Rectangular Unistrut end caps, also known as channel end caps, Unistrut caps, or channel inserts, are essential protective components designed to seal and finish the open ends of 41mm x 21mm rectangular metal channels. Manufactured from high-quality Low Density Polyethylene (LDPE) plastic, these push-fit channel caps provide a flush, professional appearance whilst protecting exposed metal channels from dust, moisture, debris, and sharp edges. Widely used across the UK's construction, HVAC, electrical, mechanical engineering, and building services industries, rectangular channel end caps are indispensable for mounting light machinery, air conditioning units, conveyor systems, and general industrial equipment.

Their primary benefit lies in enhancing safety by eliminating sharp edges, preventing contamination ingress, and providing a clean, finished look to otherwise exposed metal framework. Available in black, grey, and white colourways, these versatile channel fittings accommodate various aesthetic and functional requirements whilst maintaining excellent durability and ease of installation.
