For those who prefer a nonmetal, twist-lock fastener you cannot beat Permalock. Manufactured from DuPont's noncorrosive, UV stabilized Zytel, Permalocks are very durable (except when placed where they can be stepped on) and hold up well in the sun. Sold Each (Complete Set).

Installation is easy. The stud is secured with rivets and a backplate or with screws (with rivets requires snap fastener installation tool). The eyelet is simply squeezed together by hand and the hole cut out with a hot knife or scissors. Black in color.
