About this listing

Sold for the job site: fill the gap, then seal over it. Each piece measures roughly 72 inch long by 4 inch across, with a solid core, moulded from ‎polyethylene foam.

Expansion joints, window perimeters and any gap too deep to fill with sealant alone The maker notes: Ideal Depth Control for Sealants: This foam rod acts as a precise depth gauge, ensuring proper joint dimensions for optimal sealant adhesion and flexibility without requiring a bond breaker.

Size the rod about a quarter wider than the gap, roll it in with a blunt tool so the skin stays intact, then tool the sealant over the top. Prices here follow the listing; the figure at the checkout is the one that counts
