Heavy Duty Bathroom Locks & Unsprung Knob Sets

What are Bathroom Locks?

Bathroom locks are locks which are specifically designed for bathrooms. They consist of a thumbturn on one side which is used to lock and unlock the door via a thumbturn spindle within the handle, with a coin and release thumbturn on the opposite side which allows the door to be unlocked with a coin in an emergency.

Our bathroom on backplate lever sets are equipped with a fixed thumbturn, whereas our door knobs and lever on rose handles are not, meaning you'll need to purchase a thumbturn separately.

Components Explained

Unsprung Knob Set - all of our door knob sets are unsprung which means that they rely on the spring within the lock/latch to return to their original position.

Heavy Duty Sash Lock - designed for use with any of our unsprung knob sets. This lock is mortised into the door and screw fixed in using wood screws.

Threaded Spindle - a standard split spindle designed for doors with a maximum thickness of 44mm. If you have a door which exceeds 44mm thickness, we can supply you with a longer spindle to ensure the product functions correctly.

Thumbturn Spindle - a standard 5mm spindle designed for use with our thumbturns.

Thumbturn - a small contraption which can be turned to operate the lock from the inside. From the external side, the lock features a coin-release thumbturn to allow the door to be unlocked during an emergency.

Receiver Plate - fitted to the frame of the door and screw fixed in to house the latch and lock when in use.

Wood Screw Fixings - matching screws used to fit the products to a wooden door.
