Extra Master Blocks™ for ATVs

Model Number: MB2

Extra heavy duty 2-way mounting base attaches securely to an ATV using two u-bolts. Molded nylon with metal insert is lightweight but strong.

Master Blocks™ mount solid to ATV railings, bars and metal cargo racks up to 1" in diameter. Unlike any other mounting block the Master Block™ has unique patented micro grooves on the bottom that keep the base from slipping or twisting.

Comes as a pair and includes all mounting hardware required for installation on an ATV.
