Group Pic Group Pic Compression Mounting Clamp Assemblies

Each complete Wakefield Engineering Compression Mounting Clamp and Crossbar Assembly (130-D Shown on left and 130-A Shown on right) consists of one epoxy-coated steel crossbar and one matching spring assembly, each of which must be specified and ordered separately. Crossbar part numbers are indicted with an alpha character suffix (e.g., 130-A) and spring assembly part numbers are indicated with a numeric character suffix (e.g., 130-1).
