Unlike metallic niches, Jiffy Niche 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 Jiffy Niche to offer true bottom line savings in materials, as well as time to install. Jiffy Niche currently comes in 1 model for vinyl/fiberglass pools and spas. When paired with Hayward AstroliteTM or Astrolite IITM light fixture, you have the best quality and value in a lighting system available anywhere. To facilitate installation, all Jiffy Niche fixture housings are packed with U.L. listed conduit fittings (elbow and reducer).
