| To achieve maximum splice life it is important that the splice is properly installed. An improperly installed
splice�either under clinched or over clinched�can result in shortened splice life. |
How To Achieve an Optimal Splice:
Selecting the correct fastener based on the belt thickness, minimum pulley diameter, and application conditions
is the first step to properly installing a Clipper® splice. The second, and most crucial factor, is ensuring that the
leg of the hook is embedded 1/3 to 1/2 its thickness into the belt. It's easy to measure/inspect the splice for
proper embedment; simply follow these four steps:
| Step 1: |
Measure the belt thickness. |
 |
| Step 2: |
Install the fasteners into the belt. |
| Step 3: |
Use a micrometer or caliper to measure the finished splice.
Be sure to capture both the short leg knuckle and the
adjacent long leg in one reading. See picture. |
| Step 4: |
If you have properly embedded the fasteners, your
measurement should be between: 1) Original belt thickness
plus the value in column C, and 2) Original belt thickness plus
the value in column D. See the example and chart below. |
Example: Belt thickness: .100" Hook size: #1 (.040" wire diameter) Finished splice thickness should measure .140"- .153" (.100"+ .040"=.140" and .100"+ .053"=.153")

Other Critical Elements of a Good Splice:
- Hook points should slightly penetrate the opposite side of the belt.
- Hook legs should be parallel when installed. The knuckles of the hooks should not be higher than the legs.
- Do not lace entire width. Leave 1/4"-1/2" on each edge unlaced.
- Use one more hook on leading edge than trailing edge of belt.
- Chamfer/notch trailing edge.
- Belt edges should line up when laced ends are connected.
