The 4ft Ultra Arm Crossarm is a rugged, all welded aluminum cross-arm assembly for freestanding docks. The Ultra Arm helps eliminates the "wiggle" that can be experienced with traditional round pipe cross-arms. The Ultra Arm cross-arm is designed to be used in conjunction with 2" dock post.
Crossarm assemblies make a connection between two vertical dock posts that support your dock section. With the use of the included stringer brackets, the crossarm connects directly to your existing outside dock stingers. This cross arm features a simple single set bolt for adjusting your vertical posts to the desired height.
PVC Post Sleeves for easier post adjustment
