Compression latches for deep doors
1 min read
Lockable T handle, wing knob, square key, and L handle variants have been added to its 1000 program of IP 65 compression latches by EMKA.
"All have shaft extensions to suit even deeper door frames - up to 95mm deep", says Andy Billingham. "This is especially useful in acoustic cabinet, generating set installation, refrigeration, on-board vehicle, and heating, ventilating, and air-conditioning situations.
"Not only does this extensible shaft provide additional depth capability but it also permits manual clamping set-up by means of a threaded adjustment at the inner end. This enables the compression action to be fine-tuned by means of a shaft-mounted lock-nut."
EMKA's 1000 program provides a 6mm axial clamp function. After closing, when the lock is turned for its first 90º, the tab is rotated 90º, then stops. As the lock is turned a further 90º this is translated into linear motion which brings the tab 6mm towards the door thus clamping securely on to the door frame. "This ensures that a high degree of vibration resistance is achieved", says Andy Billingham, "as well as added clamping force on the gasket and a 'soft' closure action on the door frame. Unlocking is by reversing the process."
