Frequently Asked Questions

Q: What is an 86-type dark box and will this kit fit mine?

A: The "86-type" refers to the standard 86 mm × 86 mm wall-mount back cassette (also called a dark box or junction box) widely used for electrical switches, plug sockets, and outlets. This repair kit is specifically designed for that standard format and supports a mounting span of 65–75 mm, making it compatible with the vast majority of 86-type cassettes found in residential and commercial walls.

Q: How do I install the repair clip?

A: Turn off power to the circuit at the breaker before starting. Remove the wall plate and carefully pull the socket or switch forward. Slide the iron repair clip into the damaged mounting channel of the back cassette, align the screw hole, and tighten the included screw with a standard flathead or Phillips screwdriver until the clip is firmly seated. Reinstall your socket or switch and replace the wall plate. Power can then be safely restored.

Q: Can this kit be used for both light switches and power outlets?

A: Yes. As long as the back cassette behind your switch, outlet socket, or electrical plug is the standard 86-type format, these repair clips and screws are suitable for all of them.

Q: Is any special tool needed for installation?

A: No special tools are required. A standard flathead or Phillips screwdriver is all you need to complete the repair quickly and securely.
