Series R167 - snap-open on both sides in the inner radius 1. Double stop dog for strong unsupported length 2. Effective chip protection even against hot chips 3. Covered pin/bore connection 4. Lateral glide surfaces for side mounted operation 5. Snap-open lids along the inner and outer radius 6. Lids can be swiveled from the left to the right 7. Space-efficient with optimized ratio of inner dimension to outer dimension 8. Universal KMA mounting brackets with attachment capability on all sides Inner widths Bi: 1.97 up to 9.84 (50 - 250 mm) Bending radii R: 3.94 up to 11.81 (100 - 300 mm) Pitch: 2.31 (58.8 mm) per link = 6 links/ft (17/m) When to use Series R167 If snap-open accessibility along inner or outer radius is required If a low-cost, lightweight Energy Tube for many types of applications is required If flush attachment is required If chip-repellent features are required When not to use Series R167 If snap-open accessibility along both radii simultaneously is required System E4/100, Series R780 If very smooth travel due to small pitch is required Model R, series R68
