Socket block compatibility issues between different manufacturer vests and arms
17 years old. Gear and prices may have changed since.
What the thread found
- Socket blocks from different manufacturers may have varying tolerances that prevent proper fitting between arms and vests from different makers
- PRO manufactures socket blocks with tighter tolerances than some other manufacturers
- Incompatibility can occur even between arms and vests from the same manufacturer, suggesting tolerance variation across production batches
- Minor polishing of high spots on an arm can resolve fitting issues caused by tight socket block tolerances
Depends on
- The discussion references historical tolerance issues from manufacturers no longer in production
- Specific measurements and years of affected equipment are not clearly documented
- The solution described involved manual fitting rather than a systematic fix
- Rental equipment compatibility cannot be guaranteed without pre-testing
