Aluma-Form Aluminum Alloy Band-Type &
Wing-Type Cluster Mounts

Both cluster types are:

Fast
Lineman can install transformer-ready in 5-10 minutes even on hooks. These units are completely pre-assembled at the factory and include all needed hardware.

Strong
Super-strong and corrosion-resistant 6061-T6 aluminum alloy extruded components for high strength. No stronger band-type cluster available.

Safe
Most importantly our units are fast, easy and SAFE to install on the pole. Light-weight, boxed units are also easy and safe to store.

Band-Type Cluster Mounts

Wing-Type Cluster Mounts

We offer a complete line of compact, light-weight wing-type cluster mounts for mounting up to three 250kVA transformers. Unique design eliminates welding. Rigid, pre-assembled mounts are constructed of interlocking 6061-T6 aluminum extrusions and offer the utility a broad range of outstanding features.

No welds
Unique design eliminates welding. Interengaged extrusions allow utilization of the full strength of the metal which otherwise has to be derated in the area of any weld in accordance with recommended design parameters of A.S.C.E. Only Aluma-Form clusters are made without welding.

Rigid one-piece construction
Rigid pre-assembled mounts are easy to handle, provide excellent climbing space, look better when installed, and stay that way.

Strong, compact lightweight
Interengaged 6061-T6 aluminum alloy extrusions provide the strongest and lightest weight assemblies possible. Easy to handle and maintenance free.

Can be assembled on ground
If desired units may be prewired on ground and hoisted into position on pole.

Pre-assembled
One piece assemblies are ready to install as received without any adapter plates for ANSI/NEMA “A” or “B” lugs. 167kVA & larger transformers having dual bolt ANSI/NEMA “C” lugs can be mounted with any standard ANSI/NEMA type C adapter.
