Frequently Asked Questions

Q: What types of electrical boxes are these cassette screw support rods compatible with?

A: These electrical box repairers are designed for 86-type and 118-type switch socket bottom boxes, which are among the most widely used wall-box standards for light switches and power outlets in homes and commercial buildings.

Q: How do I know which size to use — 86-type or 118-type?

A: Measure the internal span of your existing socket box. If it falls between 69–85 mm, use the 86-type setting. If it falls between 50–62 mm, use the 118-type setting. The rods are adjustable within each range, so you can fine-tune the fit to your specific box.

Q: Is any special tool required to install these repairers?

A: No special tools are needed beyond what's included in the kit. A wrench is provided in the package. Simply insert the support rod into the damaged box cavity, adjust the length to fit snugly, and tighten the screw using the included wrench and nail head mechanism.

Q: Are these safe to use on energized electrical boxes?

A: No. Always switch off the circuit breaker and confirm the box is fully de-energized before performing any repair. These are mechanical repair accessories, not insulated electrical tools.
