No changes allowed for this design. Our custom solid or collapsible mounts provide more size flexibility.

Standard Solid Mounts fitting requirements:

  • Tubes up to 13.1" outside diameter, or with mounting rings up to maximum 13.6" outside flat to flat.
  • No more than 23" of swing-through room. Measuring balance point.

Kits arrive rough sanded. All parts included. Screw and dowel holes all predrilled and countersunk. Requires fine sanding, paint or finish, gluing bearing on laminate and assembly. Finished mounts arrive complete but disassembled. Assembly is quick and easy, advice if requested.
