The Caterpillar 4W-2109 Tube Brace Retainer is a high-strength structural clamping component. It is engineered to secure dual internal segments or clamp fluid lines directly to fixed engine mounting surfaces, absorbing structural vibrations to prevent shifting, pipe abrasion, and premature joint fatigue.
1. Core Dimensions & Weight
- Thickness Profile: 8.00 mm (0.315 in) heavy-duty steel plate.
