QUICK LOCK PRO

Incredibly well built device. Be careful though, don't let either holder arm slide off the rail. If you do, the bearings will everywhere. BY THE WAY, excellent customer service department.

High quality product, best of the ones i have tried. Suggestions: Taller holders (on the same rails), Strong Magnet in the feed to grip to metallic surface instead/in addition to the rubber feet that do not hold all that great, Third hand accessories in addition to the holder, at least 2 bendable necks with alligator jaws to assist. Make then attachable to the rail or on a longer rail

Very good quality product. Got one and after I used it, I I immediately put the second order in. Now waiting on the second one so I can use both together for the larger PCB. Highly recommended
