Each group of locks will then receive keys.

5/10 Security Rating

The Union 1148 Deadbolt is a robust surface-mounted rim lock specifically designed for timber doors. Functioning as a manual deadbolt, it provides a high level of security by requiring a deliberate action to engage or retract the bolt, unlike self-tripping spring latches.

This lock case is typically used on external doors in residential settings. It is an ideal choice for replacement installations where the existing lock body has worn or failed, or for new installs where a specific cylinder finish or security level is required separately. The unit is fully compatible with standard UK rim cylinders, allowing for flexibility in keying options such as master keying or keyed-alike suites.

The mechanism is operated via a lever handle on the internal face of the door and by a key through a rim cylinder from the exterior. It is designed to accommodate a wide range of door thicknesses, generally between 35mm and 60mm, making it a versatile solution for most standard UK timber door sets.

FAQs

No unfortunately not, the BS3621 nightlatches can not be reversed. The only way to do this is to install a standard nightlatch from our outward opening nightlatch section and then also install a BS3621 deadlock. This deadlock will give you the insurance rating required.

You need to make sure the lock you fit is NON deadlocking. This means that you can not lock people into the property. There are a few nightlatches designed for these doors. The best is the Yale PBS3 or PBS4 or a more standard model would be the Yale 88 or 84.

The best locks for these would be the a rollerbolt style lock with a masterkeyed cylinder. I would not recommend installing a standard Nightlatch on these doors as the tenants can lock themselves out if they close the door behind them. We can supply these locks for you on a masterkey if you require or keyed differ if you would prefer.

The backset on these locks is the distance from the edge of the door to the center of the Rim Cylinder. This is the large 32mm hole drilled through the door. There are 2 main sizes of these, 60mm or 40mm. Easiest way to find out what you have is to measure from outside of the door from the edge to the center of the keyhole. If you have a solid door you should use the 60mm backset locks, if you have a glass panelled door then you may need to use the 40mm backset. If your current lock is 50mm backset you will need to see our Union locks as only Union made a 50mm backset lock in the past.

There are different levels of security you can have with all locks. The standard locks (i.e. Yale 77, Yale 88) , then the mid level locks which can be key deadlocked from outside ( Yale 89, Union nightlatches). The double locking versions are only suitable for homes with other means of exit as you can lock people inside the house if not careful.

All the extra keys for the locks are cut to the specific locks that have been ordered.

With most locks that are altered to make them keyed alike you will only get 1 x set of keys with them. So if the locks normally come with 2 you will only get 2 keys total and if they come with 3 keys you will only get 3 x keys total when ordered keyed alike.

No, this product is the lock case only. To operate the deadbolt from the outside, you will need to purchase a standard UK rim cylinder separately.

The Union 1148 deadbolt is designed for installation on doors with a thickness ranging from 35mm to 60mm.

From the interior, the deadbolt can be locked or unlocked using the integrated white thumb-turn handle. Once a compatible cylinder is installed, it can be operated from the outside using a key.

This deadbolt case is designed to work with any standard UK rim cylinder, allowing you to choose a cylinder that matches your existing keys or security requirements.
