Fitting the DAESSY Rear Folding Mount - DRFM6
Selecting the Frame Clamp Location
Background
The DAESSY Rear Folding Mount – DRFM6 can be mounted on either the left or right side of a wheelchair as defined from the position of the person seated in the wheelchair. A standard Frame Clamp Inner Piece (UFCxxxxIP) requires slightly more than two inches of length and three-quarter inches of space above and below the wheelchair frame tube to which it will be clamped. There should be sufficient room for a hand to reach behind the behind the tube to tighten bolts. It does not matter how the wheelchair frame tube is oriented because the Swivel Clamps allow the Offset Links and Rear Folding Adapter to be rotated to any angle relative to the Frame Clamp Inner Piece.
Caution:
The selected location must be part of the wheelchair frame, not a removable armrest or footrest.
The Rear Folding Adapter must be located 2" to 5" below the seat of the wheelchair and partway down the side of the wheelchair at a point midway between the In-use and Folded positions of the mounted device. Offset Links are used to span the distance between the Frame Clamp Inner Piece (UFCxxxxIP) and the Rear Folding Adapter (RFA). When there are two or more possible locations the UFCxxxxIP should be placed as close as possible to the required location of the Rear Folding Adapter.

Obstructions
In addition to spanning the distance between the Frame Clamp Inner Piece attachment location and the required position of the Rear Folding Adapter, Offset Links and Frame Clamp Spacers may be used to avoid obstructions and interference with other wheelchair fittings. More information on Frame Clamp Spacers and Offset Links can be found in Connecting Frame Clamp Inner and Outer Pieces. It is important that no part of the Frame Clamp Assembly interferes with movable parts of the wheelchair such as caster wheels or brake levers. The Side Tube of the DRFM6 must not contact any part of the side of the wheelchair as it moves through its folding sequence.
Quick Check
A quick check for a suitable location for the Frame Clamp Inner Piece is to find a part of the wheelchair frame tube which has enough space to be gripped by three fingers when reaching from inside the wheelchair frame.
Unusual Situations
Some wheelchairs do not have any tubing freely accessible on the frame or do not have a tube frame. When a seat pan restricts access to the upper edge of the wheelchair frame tubing, it may be possible to use a Side Mount Frame Clamp Inner Piece, which requires no clearance on the topside of the tube and only 1 1/4" clearance on the bottomside. When the wheelchair does not have a tube frame it may have boltholes or other possible attachment methods in a suitable location. In some cases a Bolt-on Adapter may be substituted for the Inner Piece. More information on the complete range of available Frame Clamp Inner Pieces can be found Frame Clamp Inner Piece Styles.
Steps in Fitting Procedure:
Fitting the DRFM6 has the following steps:
- Selecting a Frame Clamp location
- Specifying the Frame Clamp size
- Determining the Location for the Rear Folding Adapter
- Determining the Side Tube length and Offset Links required
