Our JNT-GS-4 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:
• .190 width x .180 depth
• .100 width x .200 depth
• (2) .120 width x .280 depth that can be “customized” by the customer
See all our Groove Spreaders for various "tongue" sizes: JNT-GS-1, JNT-GS-2, JNT-GS-3, and JNT-GS-5.
