Bolt vs Retainer — How to Choose
| Criteria | Urethane Bolt | Single Flange Retainer | Double Flange Retainer |
|---|---|---|---|
| Function | Bolt + cushioned engagement | Retention flange (one side) | Retention flange (both sides) |
| Noise Level | Low (urethane absorbs impact) | Standard | Standard |
| Mounting | Through oval hole, threaded into plate | Over bolt, against link face | Over bolt, flanges on both faces |
| Best For | All tension link installations | Plate-sandwiched links | Edge-mounted or exposed links |
Compatibility Reference
Tension Link (any type)
Match bolt diameter to link hole width. Match retainer to link thickness.
1× Urethane Bolt + 1× Retainer per hole
One bolt passes through each oval hole. One retainer secures the bolt from the opposite side.
