Rated 5 out of 5 by from Simple and cost effective connector box. To satisfy the latest regulations I needed a screw-less junction box which, after installation, would be out of site. There are several types available and some are quite costly however, the Hylex Debox Screwless Connector Box came out top of the list for price and ease of use. It is an in line box in that the supply enters at one end and the feed exits the other end unlike many others where the supply and feed out are at the same end which is a little awkward when working in a narrow space. For a first time user it is wise to have some practice with the clamping system first. The connector block is about the same size as the earlier screwed type but uses four clamps on each side in place of screws. To insert a wire push it (after removing approx. 5mm of sheath) into one of the holes (there are 3 for each clamp allowing multiple connections) while pressing down on the clamp button. On releasing the clamp button the wire is gripped firmly. If the wire can be pulled out it usually means it wasn’t inserted far enough. On the opposite side of where the wire has been inserted there is another set of holes with a separate clamp that aligns with the first clamp. Repeating the procedure for inserting the wire (pressing down the second clamp etc.) you will complete the connection between the two wires. There are three more pairs of similar connections which means you can connect a 3 core and earth cable quite easily if required. At each end of the connector box is a push fit cable lock which effectively stops the cables being pulled out of the box accidentally. Once the connections are completed a hinged cover can be closed and a locking pin inserted. The box can be permanently screwed onto a beam or similar using the tabs attached at each side. All in all a very effective and completely screwless connector box at the right price.

Rated 5 out of 5 by from Cheap and cheerful Good push fit connectors but flimsy plastic for a firm fixing. Good for the price.

Rated 5 out of 5 by from Best junction boxes ever Used these a few times now and I won't use anything else from now on. Saves so much time with the maintenance free push-fit style connections. Great that you can also release too. Toolstation price is the best I've seen too..

Rated 5 out of 5 by from Seldom use anything else now I have now purchased these on several occasions. These combine maintenance free connection with a convenient box and the connection can be released if needed. These save time, look neat and cover most junction box needs.
