Not Sure If It Fits?
Our team can help you select the correct lock and mortise for your door.
Slim Series S31B Mortise Description
The AUSLOCK Slim Series S31B is supplied with a Euro-style mortise, as shown in the image beside this description. The swing size listed above refers to the distance from the faceplate to the centre of the spindle hole. For example, if the image shows 35mm, that is the relevant backset measurement for that option.
A larger swing size means the lock body will sit further in from the edge of the door.
To engage the lower deadbolt positioned beneath the latch, lift the handle upward from either the inside or outside of the door.
Please note: For full mortise sizing details and additional dimension information, please refer to the Downloads page or contact AUSLOCK for further support.
