Our JNT-GS-1 groove spreader is made out of the same red Celcon plastic as our JNT411B60 and JNT411B90, which are Boeing Approved. Celcon is a more chemically resistant plastic when working with solvents.

This spreader measures 3” square and 1/16th thickness, with four “tongues” designed to spread sealant into grooves.

Tongue sizes are:

.120 width x .090 depth

.080 width x .100 depth

.060 width x .090 depth

.120 width x .100 depth

See all our Groove Spreaders for various "tongue" sizes:JNT-GS-2, JNT-GS-3, JNT-GS-4, and JNT-GS-5.
