Ermes Block 6 Titanium is a unique design single block made from stainless steel and titanuium components with two pulleys in a choice of full Delrin, or with ceramic bearings. Block allows the attachment of up to 6 rubbers for scaled inverted systems.

This is a specially designed pulley system for neatly containing, organising multiple bands and allowing easy access for interchange of rubbers in invert-pulley roller spearguns.

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

Measurements of each pulley = D22 x H5 (Ceramic bearing)

Measurements of each pulley = D18 x H5 (Full Delrin Pulley)
