Bi-Fold Multipoint Refurb Kit

The Liniar Bi-Fold Multipoint Refurb Kit is a genuine replacement kit for the repair of reverse action Liniar bi-fold door locks. This kit contains all necessary components to refurbish multipoint locking mechanisms used in bi-fold doors, including the main gearbox, and 2 hook cases configured for lift lever operation.

This refurb kit includes a main gearbox incorporating both latch and deadbolt functions, and two hooks. The lock operates with a single 8mm spindle and features a 35mm backset. The PZ centres measure 92mm, which corresponds to the standard distance between the spindle and cylinder centres. The kit is non-handed, allowing installation on either left- or right-hand doors. The cylinder type is euro profile. The overall height of the gearbox is 233mm.

Fitment & What to Check

Confirm the backset measurement is 35mm to match the door preparation. Measure the PZ centres to verify the 92mm spacing between spindle and cylinder. Ensure the spindle size is 8mm and that the lock’s height of 233mm fits within the door’s lock cavity. Check door handing is not a factor due to the non-handed design. Confirm compatibility with euro profile cylinders.

Common Ordering Mistakes

• Ordering kits with incorrect backset or PZ centres for the door lock
• Confusing single spindle with double spindle versions
