0263R - Oetiker® DualHook Adjustable Ear Clamps

• Recommended for CVJ aftermarket for TPE and rubber boot applications.
• Designed to use with applications where high performance and universal features are demanded. 

Stainless steel, material no. 1.4301 / UNS S30400

• Tongue-in-groove design: provides Stepless® feature for the whole adjustable range and a smooth sliding into the recess
• Optimized interlock design: three dual hooks provide extra high force
• Waved band edge with dimples: enhances band strength and avoids risk of breakage
• Burr-free strip edges: reduces risk of damage to parts being clamped

Closing of clamp: To engage the clamp into the right position, the operator needs to push the band as far as possible so the hook will be engaged with the window of the minimum possible diameter. All three hooks on the upper and lower band must fully interlock. When properly closed, the tip of the hook from the lower band is visible from the outside. Waved band edge with dimples: For easy handling waves at both band edges provide equal stiffness along the band. This feature further enhances the band strength and avoids the risk of breakage as well as twisting and turning of the clamp on the band. Tongue-in-groove design: The clamp has a special recess to accommodate the tongue for the whole range. The tip of the tongue is specially designed to allow for a smooth sliding into the recess while providing the Stepless® feature. Force-priority closure: The ear of the clamp should be closed at a uniform rate not exceeding the recommended maximum closing force 3800 N. This will ensure that the clamp tension remains constant without overloading individual components of the assembly being joined, and of the clamps. Oetiker® calls this assembly method “force priority”. Force priority ensures that tolerance compensating features of the clamp remain functional for every assembly. This ensures the resulting radial force remains approximately the same for every assembly, independent of any component’s dimensional fluctuation. For disassembly, use HCC519 hand clamp clutter.
