Burg Wächter MZ 23 SB Drawer Lock, 25 mm Polished Brass Cylinder

If you need a key-operated lock for a drawer or other furniture, the Burg Wächter MZ 23 SB is a screw-on cylinder lock with an adjustable backset. Its cylinder is 25 mm long and finished in polished brass. The box contains one lock. Would the adjustable fitting range suit your furniture? That is the main detail to weigh up before choosing it.

How it fits

This is a furniture lock rather than a general-purpose door lock. Its adjustable backset runs from 15–40 mm, giving some flexibility when positioning the fitting on a drawer or cabinet. The lock screws on, and the supplied brass pin cylinder is 25 mm long. Those details make it worth comparing the lock with the existing fitting or the available space on the furniture before ordering, the product information does not give a specific drawer thickness or installation template.

For a straightforward replacement, the useful starting points are the backset range, cylinder length and the way the lock attaches. If you are fitting a lock to new furniture, consider where the cylinder will sit and whether a key lock is the access method you want. The stated dimensions of the item are 9.5 x 3.7 x 17.2 centimetres, but these are overall item dimensions, not a stated cut-out size.

What you’ll notice day to day

The key-operated mechanism gives a simple way to secure furniture without relying on an electronic or combination system. The polished brass finish is a visible part of the fitting, so it may suit furniture where a brass-coloured cylinder works with the existing hardware. Its modern style is also noted in the product details, although the finish is the more practical point to compare if you want a consistent look across handles and locks.

In everyday use, this is suited to a drawer or cabinet that needs a conventional key lock. It is a more specific choice than a basic non-locking drawer fitting, while a multi-lock system may be a better route where several pieces of furniture need to work with the same key arrangement. Keyed-alike and master-key versions are mentioned as available options, but the box contents for this item are one furniture lock, not a set.

Worth considering if you want a single screw-on furniture lock, a 25 mm cylinder and an adjustable backset. Better avoided if you need several locks supplied together as one keyed-alike or master-key set, this pack lists one lock only.

Is it worth it?

The MZ 23 SB is a focused option for someone replacing or adding a key lock to furniture, rather than a complete hardware set. The adjustable backset is useful where the fitting position needs some latitude, and the polished brass cylinder gives a clear finish choice. The main decision is whether the lock’s 15–40 mm adjustment and 25 mm cylinder match the furniture and installation space. If they do, its purpose and contents are easy to understand, if you need a shared-key arrangement across several locks, choose the relevant system option rather than assuming it is included here.
