Contact SupplierPlastic Square End Cap 40x40 mm – Heavy-Duty Ribbed InsertDescription:
The Plastic Square End Cap 40x40 mm is a durable, ribbed insert designed to fit snugly into square metal tubing with a 40mm x 40mm profile. Made from high-impact-resistant plastic (typically polyethylene or polypropylene), it provides a clean finish while protecting both the tube ends and the surfaces they rest on.
Its ribbed shaft ensures a secure, non-slip fit, even in slightly irregular or worn tubes. Commonly used in furniture, industrial frames, gym equipment, fencing, and metal fabrication.
