Daessy MH3/IPA – Multi-hole Inner Piece Adapter


The Multi-hole Inner Piece Adapter is used in place of a standard inner piece when no tube is available to clamp around and when a square frame tube has existing bolt holes for attachment of accessories.

The MH3 part has seven countersunk bolt holes spaced at 1/2″ increments and two rows of seven threaded holes spaced at 1/2″ increments. The Inner Piece Adapter is attached with bolts into the threaded holes of the adapter after the component has been installed onto the wheelchair. It is possible to attach the MH3 part with bolts through the countersunk holes and nuts on the inside of the wheelchair frame or with 1/4″ bolts through the wheelchair frame and threaded into the threaded holes of the MH3 part. The overall length of the MH3 is 4″. If less than 4″ of clear length is available on the wheelchair frame tube it may be possible to instead use the MH2/IPA.

The MH3/IPA Multi-hole Inner Piece Adapter is used with a TNUT (track nut) to fit the seat frame track system on some wheelchairs (i.e. Invacare, Pride Mobility & Quantum).  For round tube with bolt holes see the Multi-hole Round Tube Adapter.
