Less force required to move
Saves space over multiple arch J-1
Multiple wide arch available
Made in U.S.A.

Redflex® J-1W Wide Arch Expansion Joints are engineered
to permit greater movement capabilities than standard J-1
Expansion Joints. J-1W Expansion Joints can be used to
alleviate more extreme expansion and compression stresses,
without the need for double or triple arches, since the J-1W
has the same face-to-face dimensions as the standard
J-1 Single Arch Expansion Joint. The wide arch design
also reduces the amount of force required to cause movement in the expansion joint while allowing the J-1W to be
used under the same working pressures as the standard J-1.
These features and benefits of the J-1W Wide Arch
Expansion Joint result in a cost savings for both new
installations and for replacement operations.
