Skull Skates "Presto" rails. Saw cut and machined high molecular weight UHMW. 14.5" x .8" x .4". A slimmed down version of the Skull Skates Stout rails for smaller decks or to ultimately save a little on weight. Still more substantial than most contemporary cheap plastic spindly rails, so definitely ready for abuse. Comes with wood screws. Torture tested. Made In Canada.
