The right belt clamp holds the belt evenly across its full width. A clamp that is too narrow pinches the middle and lets the edges slip. One that is far too wide is heavier and harder to handle in tight spaces. Here is how to size it.
1. Measure the belt
- Width: measure straight across the belt, edge to edge, in inches.
- Thickness: measure with calipers if you can. GrabUnity clamps are rated for belts up to 8 mm thick.
- Material: note whether it is cotton, rubber-covered or PVC.
2. Match width to tool
| Belt width | Tool | Load capacity | Good for |
|---|---|---|---|
| Up to 2" | GrabUnity Mini | 400 lb | Small belts, lightest clamp |
| 2" | GrabUnity V | 400 lb | Vertical and inclined belts, lowest cost |
| 2" | Aqua Belt Joiner | — | Very tight spaces, portable |
| Up to 4" | GrabUnity | 400 lb | Our best-seller for everyday maintenance |
| 2"–4" | GrabUnity Flex | 400 lb | Rubber belts |
| Up to 7" | GrabUnity Pro | 400 lb | Wider belts, anti-slip red blocks |
| 18" or 32" | GrabUnity Max | 1,200 lb | Large industrial belts, two clamps |
3. Think about the space around the belt
If the belt runs inside a machine frame or close to guards, a compact tool like the Aqua Belt Joiner is easier to position. On open conveyors with room to work, pick by width alone.
4. Consider the load
Heavier, wider belts need more pulling force to bring the ends together. The GrabUnity Max uses two clamps and is rated to 1,200 lb so tension spreads evenly across an 18" or 32" belt.
