Awesome set of tools

The following review is for BTK106, which is a part of the bundle you are viewing.

These trim tools came in handy and were a big help. Great value for these tools.

Very slick tools to efficiently slip wires/cables into car interiors

The following review is for BTK106, which is a part of the bundle you are viewing.

This kit was recommended by the Sonic Professional Installer staff to slip a wiring harness from the trunk beneath leather seat corner, beneath door entry panels into plastic wire channel, and on through the dash of a 96 Lincoln Town Car. I was dubious that it would be needed but found it protected the continuity of wire insulation, made the job easier, and was indispensable for removing the plastic fasteners holding the knee protection panels beneath the dash. Most home workshops do not have tools equal to the job that can prevent gouges and mars in these expensive interior panels. They are sturdy and well worth the price.

Don't go without it

The following review is for SDBSK2, which is a part of the bundle you are viewing.
