It takes alot more strength and effort to bend metal when its 10 feet long. They made it look easy with that small piece.😂

Try hemming a full size piece… That brake is garbage. The last van mark I will ever buy. Bought a brand new metal master 14’6. Notice how he says pre load the hinge to hem? Try hemming a full size piece. Damn near impossible. Called van mark and they directed me to a pdf that says “slightly lift piece up before hemming”. In short, its a design flaw. And if you have a full size sheet, hemming will take multiple attempts of “preloading the hinge”. Other brakes hem without effort. This one, you need all 8 planets to align with the sun to get it to hem. Van mark lost a customer for life after I disposed of my brand new metal master that was only used on one job for half the price I bought it for.
