Replacement Suspension for Super-V

The MSA Fas-Trac III suspension replaces the original liner in compatible Super-V hard hats. It uses a four-point ratchet system to secure the shell to the wearer’s head. The unit is supplied new and fits most standard hat sizes. Workers needing a fresh suspension for an existing MSA helmet use this part.

Four-point ratchet capacity and limits

The four attachment points distribute force across the crown during impact. The ratchet mechanism allows quick tightening without removing the helmet. It does not add ventilation or accessory slots beyond the original shell design. Helmets with six-point mounting patterns or non-MSA shells cannot accept this suspension.

Super-V compatibility requirement

This suspension fits only MSA Super-V models listed by manufacturer part numbers such as 10025227 and the C217091 through C217140 series. Grainger cross-references 43FE03 and 499L42 through 499L46 confirm the same fitment. Buyers must verify their helmet part number before ordering.

Questions about this item

Will the 4-point ratchet suspension fit the Super-V helmet I already use?

Yes, it is designed for the Super-V and matches manufacturer part numbers 10025227 and C217091 through C217140.

How do I confirm the ratchet mechanism is holding securely once installed?

Turn the ratchet knob until the band feels firm and the helmet does not shift when you nod or shake your head.

Does the package include a new hard-hat shell or only the suspension assembly?

Only the 4-point ratchet suspension is supplied; the Super-V shell must be purchased separately.
