Page 496 | 2.1 Tensioning, Clamping, Switching with Levers Safety tension levers GN 312 are used on such applications where a thoughtless or mistaken releasing or re-positioning of the tension lever could lead to an accident. The lever in its rest position is not connected with the internal spindle and can be rotated unhindered. The tension lever engages in the serration only after pushing it down, thus allowing clamping or unclamping. The „freewheel“ position is re-established as soon as the handle is released. see also... • Safety Hand Levers GN 604.2 (Plastic) → Page 494 Information GN 312 Safety Tension Levers Push to Engage 1 d 1 2 d 2 3 Type How to order 1 2 3 GN312-21-M8-E 3 Type E Angled lever D Straight lever • Steel Blackened • Ball knobs DIN 319 Plastic, Duroplast Black, shiny finish • RoHS Specification 1 2 d 1 d 2 d 3 d 4 d 5 h 1 h 2 h 3 h 4 h 5 l 2 l 3 t Type E Type D Stroke Type E Type D min. 21 M  6 M  8 13,5 8 20 37 34,5 4,5 62 39 3    75 81 70 11 24 M  8 M 10 16   10 25 44 41    6,5 78 47 3,5 101 108 96 14 28 M 10 M 12 19   12 30 53 49    8,5 93 56 4   116 124 110 17 33 M 12 M 16 23   12 32 60 56   10,5 105 65 4,5 131 140,5 124 22 • With inch threads On request
