RAM® 4" Long PVC Pipe

I used this pipe to extend a mounting arm for my GPS, and the 4-inch length was exactly what I needed to clear a vent. The fit onto the RAM ball is snug with no wobble, which was my main concern. It feels solid enough to hold up to vibration on rough roads.

Installed this on my boat's electronics mount and it fits perfectly with the other components. The 4-inch length is just right for keeping my GPS at eye level without any wobble.

Took it out of the box and the PVC feels thicker and sturdier than I expected—definitely won't flex under a heavy load. The 4-inch length was perfect for my setup, and it slid right onto the ball base without any forcing.
