INSTALLATION INSTRUCTIONS
SAVE THESE INSTRUCTIONS
Unlike metallic niches, DuraNiche™ niches are
injection-molded of PVC for superior performance,
non-corrosive durability and plumbing versatility -
plus the lowest installed cost.
The ability to accept PVC over expensive metal
conduit enables DuraNiche™ to offer true bottom
line savings in materials, as well as time to install.
DuraNiche™ comes in three models for concrete/gunite pools,
vinyl/ fiberglass pools, or for concrete/gunite spas. When paired
with a Hayward AstroLite™ or AstroLite II™ light fixture, you have
the best quality and value in a lighting system available anywhere.
To facilitate installation, all DuraNiche™ fixture housings are
packed with U.L. listed conduit fittings (reducer, elbow, and cou-
pling.)
