13mm 1000V Insulated Open-End Wrench

This 13mm open-end wrench is individually insulated and tested to ASTM F1505 standards for work up to 1000V. It features an orange outer insulation layer and a yellow inner layer that acts as a visual safety indicator. The precision-machined jaw provides a secure fit on fasteners. It is designed for electricians and technicians working on live or potentially live electrical equipment.

Upgrade from non-insulated wrenches

This tool replaces standard non-insulated wrenches when electrical shock protection is required. The jump is worth it whenever the task involves exposure to energised parts up to 1000V and a 13mm fastener size. It is not for buyers who need a different hex size, a ring or box-end profile, or a ratcheting mechanism. It also does not suit applications where insulation is not required or where a different voltage rating is specified.

Simple hand-tool use

Installation consists of selecting the correct 13mm size and applying the wrench to the fastener by hand. No assembly, calibration or software is involved. What usually goes wrong is using a wrench with damaged insulation, which compromises the 1000V protection, or applying excessive force that rounds the fastener corners. Users must inspect both insulation layers before each use and ensure the jaw fits squarely on the nut or bolt.

Questions about this item

What hex size does the MEBO13-I wrench fit?

The wrench is machined for a 13 mm hex fastener, giving a tight and secure fit on that size.

How do I confirm the insulation is still safe before each use?

Check the two-colour coating; if the yellow layer shows through the orange, the tool must be removed from service.

When should the wrench be replaced?

Replace it once the yellow safety layer becomes visible or if the insulation is cut, cracked or contaminated.
