   "GN 927 clamping levers with eccentric cam: a lever with a cam that presses a contact plate against the work as it is swung through 90°. Four lever sizes (l1 44, 63, 82, 101 mm); internal-thread forms take M4 to M10 or 8-32 to 3/8-16 and stud forms carry a stud d2 × l2. Type A has a contact plate with a setting nut to adjust the clamping force (l4 = adjusting range), type B has no setting nut (d5 in place of d4). The lever is zinc die-cast (GN 927) or steel (927.2) and stainless (927.5 / 927.7) in the same series, with the cam stroke h and the plate in steel or plastic (POM in A, PA in B). Elesa quotes clamping forces up to 8 kN for the largest size.",

Letters are the manufacturers'; b, d3 and l5 are printed without definition. Elesa gives l3 as a range for type A (13.2 to 15.2 for the 44 mm size: the setting-nut adjustment) and uses l6 for type B (15.2 / 16.3 / 19.5 / 25.3); the table shows the lower type-A figure only.
