The RAM-B-259U is designed to mount to the lip edge of a flat surface up to 1" thick. Popular mounting edges include a car side window edge lip or glare shield on an airplance. The base has two composite bolts that, when tightened, clamp the base to the lip surface. A RAM 1" diameter rubber ball is connected to the base allowing you to connect a RAM 1" diamter arm socket and connection plates to create the perfect mount for your application.
Mount will attach to flat surfaces with the following dimensions:
Min: 4.4mm / 0.17"
Max: 28.0mm / 1.12"
Extremely reliable component from a trusted manufacturer.
Very good value and quality for the price. Functions as advertised plus a few places not stated. Excellent purchase.
Product quality is good but clamp depth is too shallow. When screws are tightened they catch only the soft part of the glare shield in my Cessna 172 and does not create a stable platform for my iPad Mini mount.
Did not like. Well built but is bulky and did not fit firmly on my RV-8 glareshield ... when I put the mini ipad on it ... it was very shaky. I would have sent back but the cost of shipping and restocking make that not feasible.
