dock steel and concrete at the dock edge has been
damaged. The formed angle is required to rebuild the
damaged concrete edge for a proper installation if the
dock height is adequate.
Installation Steps:
1. Remove all existing bumper material and protruding
objects from dock edge. Clean and sweep dock
edge free of debris and flammable chemicals before
installing unit.
2. At chosen location for the formed angle, locate the
center of space and mark a point half of the angle
width to the left and right.
3. Using a proper lifting device, raise and position the
formed angle to marked position, slide formed angle
against dock face.
4. Mark along full length of back edge of formed angle.
Slide angle forward the width of brushing tool,

6. Using the back edge of the formed angle as a guide,
groove concrete approximately 5/8” deep by 2” wide,
and should be the entire length of the formed angle.
7. Slide formed angle back until tight against dock face.
drill 5/8” dia. by 5” deep holes through formed angle
at back edge. Install anchor bolts per manufacturers
specifications, and tighten securely. Weld anchor bolt
nuts to formed angle using a 1/4” fillet weld all the way

exposed through the nut, and plug weld around the
top of the nut to the anchor bolt. Ensure the top of the
