Adjustable Shower Arm Extension 10" Long - Stainless Steel Chrome Finish - The Only Arm Designed With a GEAR JOINT That Won't Slip! Our Long Shower Extender Pipe Can Hold A Rainfall Shower Head System 10 INCH EXTENSION  The arm is about 11.25 long, but will give you a 10 extension from the wall pipe to your shower head. It can then be adjusted on both ends, moving up & down with a range of 18. Perfect for any person, no matter the height! GEAR JOINT DOESNT SLIP  Our shower arm has a gear joint which locks tightly. Competitors use a normal round joint instead of our locking-type mechanism which will hold heavier shower heads. Ours has been tested & worked for 12 and larger rainfall shower heads. NO PLASTIC PARTS  Our shower arm is made of high quality stainless steel with a polished chrome finish. It is extremely sturdy and has no plastic parts. It looks pretty, but is built tough! EASY TO ADJUST  The shower arm has long knobs that are easy to grip, allowing you to unscrew and tighten quickly without any finger pain. Also, since it has a gear joint, you dont have to tighten as much as other shower arms. QUICKLY INSTALLS IN MINUTES  It mounts to the wall fitting all standard 1/2 pipe threads, and can be adjusted to swivel up and down to suit almost any height!
