NoLimitz RDM Mast/Boom Shim
The NoLimitz Skinny Mast Boom Shims are compatible with almost every boom on the market. The height between the ridges is 11.1 cm (if the height of your boom's mast wrap is shorter, this shim will work).
The mast-boom interface is extremely important and our shims provide excellent grip and stiffness for the ideal connection.
The Skinny Boom Shim insures protection from high load strain both from clamping and from rig stress.
