Ultra-light and ultra-compact progress capture pulley (volume and weight 50 % smaller than the MINI TRAXION) Excellent efficiency, thanks to sealed ball bearings (91 %) Cam can be locked in open position so device can be used as a simple pulley. Works even on frozen or muddy ropes For use on ropes between 8 and 11 mm in diameter Weight: 85 g. Working load: 2,5 kN x 2 = 5 kN . Breaking strength: 7.5 kN x 2 = 15 kN . Working load as progress capture pulley: 2.5 kN . Breaking strength as progress capture pulley: 4 kN . Certification(s): CE EN 567, UIAA.
