Nomaco HBR XL Cross-Linked Backer Rod

TYPE: 1 – Rounds of rods of various diameters intended for use with cold- and hot-applied sealants.
FORM: Round Foam Rod.

HBR XL limits the depth of the sealant and prevents excessive sealant use. It also helps sealant assume optimum shape factor to prolong sealant service life and acts as a barrier to the flow of sealant through the joint.

Common applications include, but are not limited to, expansion and contraction joints, curtain walls, construction partitions, parking decks and bridge construction where both cold- and hot-applied sealants are used.
