With a shear strength up to four times higher than standard hook and loop, the VELCRO Brand ALFA-LOK hook tape delivers industrial-grade holding power in a slim 25 mm profile. This 3-metre roll of black, self-adhesive fastener is engineered for heavy-duty mounting, display assembly, and automotive applications where a secure, long-lasting bond is non-negotiable.

Overview
