These #424-4S Slip-Fit Eye Ends are made of aluminum and fit 1/2" pipes (7/8" OD tubing). The eye ends are equipped with a stainless-steel set screw.
A preferred choice in boat top fitting hardware, Slip-Fit fittings reduce stress and time during installation. No threading is required as all fittings easily slip on or over the pipe frame and are fastened by square-head set screws. The pipe fittings also allow fast adjustment when the pipe is not cut to precise length. Slip-Fit eye ends are durable and easy to use.
