These Jump cup strips are made of tough, flexible,
UV-stabilized polypropylene plastic. The sun will
not hurt them and they will stay flexible even at
sub-zero temperatures. The jump cup strips are
very easy to install, just clip them onto your 1" or
11⁄4" PVC jumps and you are ready to go! Screws
are provided if you want to permanently attach
them. These jump cup strips will work on PVC
pipe, metal frame and wooden jumps.
