DX Engineering Rotator Top HD Mast Clamp Mounting Hardware is available here as replacement hardware for DX Engineering’s DXE‑RTMC Series Rotator Top HD Mast Clamps, used to attach these clamps to compatible rotators.

DXE‑RTMC‑MTG‑HWK – This hardware kit mounts the 2‑inch DXE‑RTMC‑2 and 3‑inch DXE‑RTMC‑3 Top Mast Clamps onto DXE‑RT4500HD and M2 OR2800 rotators. The kit includes stainless steel bolts, washers, and single‑use nylon lock nuts. This hardware kit must be ordered when reinstalling these clamps.

DXE‑RTMC‑YSU‑HWK – This hardware kit is for use only with the DXE‑RTMC‑2 Top Mast Clamp and fits Yaesu G‑2800DXA, G‑1000DXA, and G‑800DXA rotators. The kit includes bolts and washers. It is also available as replacement hardware for K7NV Mast Clamps.

This is stainless steel mounting hardware only. The hardware works with both Rotator Top HD Mast Clamps, which are sold separately in two sizes: the DXE‑RTMC‑2 for 2‑inch OD masts and the DXE‑RTMC‑3 for 3‑inch OD masts.

NOTE: Only the 2‑inch HD Mast Clamp (DXE‑RTMC‑2) can be used as a replacement for a Yaesu top mast clamp. The 3‑inch DXE‑RTMC‑3 is not compatible as a Yaesu replacement.
