This is a set/pair of knob-bolts for connecting and tightening two A-frame ramps together at the top each corner.
First tie the brace plate and cylinder cap plate together in a light contact connection, so the ramps are free of movement for setting up to a desired height. Then tighten the both knob-bolts for completing the setup. Make sure you measure bolt receiving hole size for correct size of knob-bolts ordered. We have 3/8" 1/2" and 5/8" sizes. Wrong size ordered may result spending more or redundant on shipping costs.
Quick and easy set-up!
