Federal Signal Hi‑Rise Under‑Clamp Set – Black Lower Tube Clamps (Pair)

Description

Set of Two Federal Signal Hi‑Rise Under‑Clamps – Black
Each set includes the correct‑size mounting bolts needed to attach the clamps to your TwinSonic light bar. (Bolts are included but not shown in the current photos — updated images coming soon.) All required hardware is provided to mount this set to the underside of the light bar.

This listing is for the pair of black “under‑clamps” used on Federal Signal Hi‑Rise mounting systems. These clamps secure around the stainless Hi‑Rise tube and connect to the gutter‑mount brackets on the vehicle. If your customer already has the upper Hi‑Rise tube and gutter clamps, this is the lower clamp set needed to complete the installation.
