The units are fully automatic and require no power or electricity. They are installed in the top and bottom of the inactive leaf. Closing the active leaf automatically extends the top and bottom bolts 19mm into the headframe and sill strikes, locking the inactive leaf. Opening the active leaf automatically retracts the top and bottom bolts, releasing the inactive leaf.
The patented free floating cams with a swivel face require a maximum of 3 lbs closing force. An override feature prevents damage to doors or bolts, should the bolt heads be prevented from entering either the top or bottom strikes. The bolt head rods can be vertically adjusted by 13mm for unusual clearances.
To prepare the door for installation, only two 28.6mm diameter holes are required, one at the top of the door and one in the meeting stile. The top bolt is installed first, and then the edge bolt. The edge bolt's grooved channel will engage the top bolt's grooved bottom, mating them together inside the door.
The major advantage on timber doors is that the small profile design eliminates cutting away the corner of the wood door adding stability and reducing the possibility of the veneers from splitting or delaminating.
