Great for corners in assemblies and structures (dog beds, shelving units, etc). 90 degree angle with additional upright or downward socket (depending on positioning). External connection to fit over pipe. Injection molded from 100% furniture grade PVC compound. High gloss non printed surface. Tapered ends on sockets for clean transition to pipe. Considerably more socket depth than plumbing fittings. Impact strength is typically 5 times as strong as plumbing, conduit, and irrigation fittings (based on independent lab testing). UV resistant to maintain integrity and look through years of exposure to varying weather conditions.
