Our new HVAC hinge lock meets all the criteria for securing big air-conditioning units. By using a height-adjustable hinge bracket, it also makes a precisely adjustable gasket compression possible.
As this video demonstrates, when opening the EMKA HVAC lock, decompression is effected in two steps: First the door is caught by an integrated, patented impact guard so that the pressure can escape from the vent ducts safely. Then the door is unlocked enabling access to the unit. The door can be closed in only one step, another distinctive feature for convenient operation.
