Slim Jim

The Thin Profile Backlit LED Sign is Contractor Friendly

The Slim Jim sign measures approximately 0.4” (11mm) thick and runs directly from 110V AC mains power with no additional power supply or transformer.

It fits neatly onto the US mains power single and double socket back-boxes as well as the

standard conduit boxes.  Thus, making it easy and quick to fit for contractors.

The Slim Jim is intended to be wall mounted on a standard electrical box.  Using standard

electrical boxes reduces the cost of installation in new builds.  The box for the sign can be

installed by the electrician during ‘first fix’ when the wiring is run.  This sign can be fitted

during the ‘second fix’ state when the electrical outlets and switches are installed.

The sign has a low profile so that it gives a smart almost-flush appearance without having

to make a large hole in the wall.

It is designed to give a long service life and has no user-replaceable parts inside.  Also, power consumption is a minimal 5 watts.

The Slim Jim is for indoor use only and should not be used in damp areas or places of high humidity.  However, if you need a waterproof sign, please check out our Ultra IP66 Sign.

You may use the sign on its own, or in conjunction with an interlock system.  To clarify, RT Technologies provides a full range of laser/laboratory interlock equipment including control systems, interlock switches, laser shutters, door locks, access signs, external power supplies, etc which can be connected to provide a complete interlock system.  Full support, design, and installation is available from RT Technologies.
