Holt 30mm HA2031 Multi Function Block

Holt 30mm HA2031 Multi Function Block

30mm Single Multi Function Block

The multi function block has a slightly different strap compared to the A2030.

The HA2031 multi function block is the base block used in the following variations: HA2031F, HA2031SC and all double and triple variations.

The multi function head is designed to attach our swivel, fork and cheek adaptors to. It is also used for riveting to the double and triple ultra-straps.

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
