This is a thick, 1/4" acrylic folding windshield. We don't sell the flimsy 3/16" (.177) shields, only the best. No tools required to mount, simply snaps into place. A must-have for driving when it's cold or wet, folds up when you want a breeze. Made from first rate acrylic. Rubber pads keep it from rattling. Fits Marathon (boxy look) EZGo carts from 1986-1993. Please specify Clear or Tinted.
