Clamshell rings are custom designed leaving 1/8" of space around the tube (1/16" on any side). You will need adhesive backed felt or weatherstripping to line the inside of the rings to obtain desired fit. The clamshell rings two bottom boards are joined with heavy duty anodized piano hinge. The two top board open, and secure together using a 2-1/2"x1/4-20 thumb screw passing transverally through one board and into a 1/4-20 threaded insert seated in the adjacent board, to close the clamshell. Bearings attach to 4" wide supports that attach to the ring segments. The front ring halves and back ring halves screw onto the bearing supports and top and bottom assemblies using #12 wood screws.
