Heuskay cabinet cam locks 40 mm

For someone replacing a damaged lock on a mailbox, drawer or cabinet, this Heuskay set offers four cam locks, keys and mounting parts in one package. The product name specifies 40 mm, while the description lists several cylinder lengths, so the exact size matters when matching an existing opening. Each lock turns through 90°, and the listing gives a maximum material thickness of 12 mm. It could suit a small repair where you can measure the panel and compare the lock plate before installation.

Quick overview

The locks are made from zinc alloy with a nickel finish. The stated lock plate length is 47 mm, and the package includes eight keys and some mounting parts. The description names possible uses such as letter boxes, post boxes, drawers, cupboards, filing cabinets, lockers, tabletop showcases and camper or RV doors. That range is useful if you have more than one small lock to replace, but it does not establish that every listed application will fit without checking its dimensions.

There is an important detail about the keys: the product name says “Key Alike”, but the description also says each lock has different keys. Those statements do not clearly confirm whether one key operates all four locks. Keep in mind that the cylinder lengths listed in the description are 16 mm, 20 mm, 30 mm and 40 mm, while the product name identifies the 40 mm version. Confirm the supplied length and key arrangement before relying on either detail for a multi-lock setup.

How to use it

The listing describes installation with a screwdriver. For a replacement, remove the old lock and compare its cylinder length, lock plate and panel thickness with the details provided here before fitting the new one. A 90° turn is the stated opening angle, so the cam needs room to rotate behind the panel, a cramped space or a mismatched plate could make an otherwise suitable-looking lock a poor fit.

For example, if a mailbox lock has stopped turning, measure the door panel and check the space behind it before taking the old lock out. That gives you a practical comparison point for the 12 mm thickness limit and 47 mm plate length, rather than relying on the product name alone.

Practical tips

These are replacement cam locks, not a complete cabinet or mailbox system. They make more sense when the existing lock is the part that needs changing and the panel dimensions are compatible. If you are choosing locks for several doors, settle the keying question first: eight keys are included, but the description does not clearly explain whether they are interchangeable between locks.

It suits you if you need several compact replacement locks for drawers, cabinets or a letter box and can confirm the measurements. It may not be the best choice if you need a clearly specified one-key-for-all arrangement, or if your panel exceeds the stated thickness limit. The listing also does not give detailed dimensions for the mounting parts, so the included hardware may not answer every installation requirement.

Buying questions

How many locks and keys are included? The package details state four cam locks and eight keys, plus some mounting parts.

Will it fit a panel thicker than 12 mm? The description specifies a fit for material up to 12 mm thick, so it does not confirm suitability beyond that limit.

Do all four locks use the same key? The information is inconsistent: the product name says “Key Alike”, while the description says each lock has different keys. The key arrangement is therefore unclear from the supplied details.

For your situation

Choose this set when you are replacing existing cam locks and the stated panel limit, plate length and cylinder size match your setup. Its four-lock pack is less suited to a repair where you need only one lock and already know that a specific key must operate every door. If that shared-key detail is essential, the conflicting description is a meaningful reason to look for a listing that spells out the keying arrangement.
