6、all be as light-weight as possible meeting the standards described in 3.1 and provide ease of use with any typical combat gloves. 3.1 Type I (TABLE I). The chock shall be a wedge-shaped design with the chocks width tapering from the top to the bottom and the dimension requirements of drawing X3-3-01
7、15. The chocks thickness shall be tapered from top to bottom along its width. The wire loop shall be routed through four holes in the chock (two in the top, two in the bottom). The size shall be stamped on the wider, flat portion of the chock. The wire loop cable will protrude 190 ( 13) mm on sizes
8、1 through 10; 215 ( 13mm) on sizes 11 through 13. The thickness shall be measured at the top of the chock, along its shorter side. The width shall be measured at the top of the chock, along its longer side. The chock will be constructed and comply with the size requirements in Table I. 3.1.1 Type II
9、 (TABLE II). The chock shall be constructed and comply with the size physical requirements in Table II and the dimension requirements of drawing X3-3-0116. The wire loop shall be routed through four holes in the hexcentric shaped portion (two in the top, two in the bottom). The size shall be stamped
10、 on the hexcentric shaped portion of the chock. The thickness of each hexagonal side shall vary to provide use in various sized cracks in the rock. The wire loop cable shall protrude 190 ( 13) mm on sizes 1 through 5; 342 mm ( 13) mm on sizes 6 through 11. The hexcentrics shall be measured for thick
11、ness on their parallel sides. The length shall be measured at the top along the longest dimension, perpendicular to width measurement. 3.1.2 Type III (TABLE III). The chock shall be constructed and comply with the size and physical requirements in Table III and the dimension requirements of drawing
12、X3-3-0117. The irregular chock shall be constructed to provide three points of contact with the rock. The irregular chock shall be designed to provide protection in both passive and active camming modes. The size shall be depicted on a label that is affixed to the webbing loop portion. The webbing l
13、oop portion shall protrude 190 ( 13) mm on all sizes. The width shall be measured at the point at the end of the rails proximal to the webbing. 3.2 Color. The chocks shall be provided in a low reflectance, matte finish and provide low contrast with typical use terrain. Each size shall be of a differ
14、ent anodized color (Type I and Type II only). The webbing sling (Type III only) shall be of a different color for each size. 3.3 Materials. 3.3.1 Basic Material (All types). The wedging portion of the chock shall be anodized 6061-T6 or 7075 aluminum. Provided by IHSNot for ResaleNo reproduction or n
