Holt's 20mm Micro Block range shares principles incorporated in the 40mm dynamic bearing system.
- Cold forged side straps with Holt's ropekind head detailing. The narrow strap also allows excellent articulation. - Lightning holes reduce weight and allow easy access to flush the stainless steel bearing system. - Large central hole enables line to be tied through for cascade or other purchase systems; this negates the need for an additional becket. - The recessed 6mm rivet provides greater strength in the critical bearing area
