  • Betts 4483SL002

    Note - Betts has switched to a new design swing bolt for ASME full opening manholes. All ASME manholes built since 2018 have the new design. Instead of a 'barrel' head for the swing bolt pin to go through, the head is more of a 'bulb' as in the picture. The kits listed below give you the entire new assembly to replace the older style.

    Wing-nut includes a staked-on bearing washer for decreased wear and a retention e-clip is included on top of swing-bolt to keep the wing-nut from accidentally unthreading off of the swing-bolt while opening manhole. Assemblies ending in “002” include swing-bolt pin (4463SL) and 1/8” coil pin (9Q8605).

    Please note: Older style swing bolts have a larger coil pin hole diameter; therefore, specify the “002” kit to ensure the necessary replacement components are received. For more information use downloadable file to the right.
