Ermes Sub Block Hard Pulley 3 - Pair are the latest model of invert pulley blocks from Ermes. Price is for a pair.

This is a specially designed pulley system for neatly containing, organising and bearing the load of rubbers for invert-pulley roller spearguns.

Pulleys can be separated on round barrelled spearguns or used in flat bellied spearguns close together as well.

These are openable and light weight. The body is laser cut from quality stainless steel and the pulleys are made from solid Delrin.

There is also an option to select a version with ceramic bearings for a much smoother load.

It can mount up to 3 rubbers per block, with provision to optimise and maintain their correct positioning.

These are useful to simplify attaching multiple bands and eliminate the added weight, length and complication of shackles.
