Rated 5 out of 5 by from Great Sturdy, easy to fit, plenty of knockout areas and did the job. I recommend

Rated 5 out of 5 by from Slim Backbox Great Value Great for when a slim backbox is all you need. Make sure your accessory is thin enough to fit inside a 16mm backbox. This would typically only be a light switch but these too come with a minimum depth and some will exceed the depth of this backbox. A solid slim backbox that will get you out of a difficult situation

Is there a single plug socket that can use a 16mm back box?

Asked by: Paulcx
Hello. We cannot recommend that any of our Crabtree sockets are fitted in a box with a depth of anything lower than 25mm. Thank you for your interest in our appleby brand.

Do you need a gromet with these? And if so where can you buy them?

Asked by: Daniel89999
Hello. There are a number of manufacturers to choose from. Historically, we refer to a company called Envirograf. They supply a multitude of fire safety solutions for numerous electrical applications, including gaskets for steel and dry liner boxes. Thank you for your interest in our appleby brand.

What length of electrical screw should be used?

Am I right to the think the standard length screw is too long for the box?
Asked by: Bensymon
As this product is only 16mm deep it will obviously be limited to the screw length that it can accept. It is most common that light switches are the product category most used in conjunction with the 16mm back boxes. Due to this you will usually find that the light switches have a smaller length screw than other wiring accessory products (such as sockets, 20A/45A Switches) and this is definitely the case with our own Crabtree products. Therefore to answer the question, yes, the standard length screw for a light switch should fit a 16mm box, however a standard screw for other products probably would not (or it would be very tight), the depth that the box is fitted back into the wall and if tiles are fitted would also be factors that would affect this. Thank you for your interest in our Appleby brand.

16mm deep metal back box is it ok to fix a network to a single rj45 network gang ?

Asked by: harpo2
The question is a little confusing. If you are asking whether an RJ45 will fit in the box then it depends which accessory & arrangement you are using. We would suggest a minimum box depth of 25mm when fitting Crabtree euro RJ45 modules to ensure sufficient cable space. However if the question is not related to the box but you require verification that it would be acceptable to use one RJ45 outlet for a network? This depends on the network. Telecom/Data modules have to be fitted in accordance with the required network arrangement and will need splitting for multiple combinations i.e. Telephones & Computers in an office environment...too many variables to give an answer for unfortunately. In all cases you must of course use a qualified electrician. Thank you for your interest in our Appleby brand.

Would a 16mm metal back box be deep enough to fit a light switch?

Asked by: JohnG1969
Light Switch interiors differ in wiring space, but we can advise that all Appleby metal boxes fit our electrical wiring accessory brands, ie Crabtree and Volex. Thank you for your interest in our Appleby products.
