build for long lasting performance This shower elbow adapter is made of copper material, designed to be heavy duty and durable. It is corrosionresistant and pressureresistant to ensure reliable use over time. 90 degree angle adjustment for flexible installation The 90 degree elbow changes the shower stream direction without restricting flow. It can connect a shower arm or water pipe to a shower head, and it can also attach a hand shower head. It improves the angle to enhance the shower experience and fits into tight or awkward spaces where a different angle would help. Reliable and rustproof construction The elbow adapter uses a onepiece construction to reduce leakage and damage. It resists rust and corrosion and requires only minimal maintenance. Easy to install and use Operation is simple and smooth: just hand tighten the rotating collar; no wrench is needed for setup. Practical use scenarios 1) In a small bathroom with limited space, install this 90 degree elbow to direct the shower head without crowding the area. 2) Convert a fixed shower head setup to a handheld shower head by attaching a hand shower when flexibility is needed. 3) Upgrade to a rustproof, durable connection in households with frequent exposure to water and humidity, reducing maintenance and leaks.
