| Only Mystery Electronics Backboxes ensure full compatibility
with our products. Backboxes conform to NEMA® standards and are UL® listed*.
Alignment labels aid proper installation. Trade-size knockouts for conduit
system connections are included. Appropriate mounting holes are pre-punched
and tapped for easy trim-out. |
|
Backboxes are required in concrete or masonry
and when conduit systems are used. They are also recommended
for raised wooden floor or hollow wall construction, though site conditions
may make them optional. Please see the appropriate TechNote, or call us
for application help.
