EJ-500 is supplied directly to the jobsite in a roll with detail work completed and seamed together by a proprietary vulcanizing process, which results in monolithic and elastic seamed joints. Seaming can also be done on-site if required. EJ-500 is a flat-profile elastic material manufactured from a saturated elastomer. The EJ-500 expansion joint system comes in four sizes, the EJ-500/20, EJ-500/40, EJ-500/100, and EJ-500/240, designed to accommodate specific horizontal building movements of plus or minus 1", 2", 4", and 10", respectively.
The EJ-500 expansion joint system is designed to accommodate three-way building movements.
