Fitting the DAESSY Rigid Mount - DRM1 and DRM1ROP
Selecting the Frame Clamp Location
Frame Clamp Location
Comprehensive information for selecting a Frame Clamp attachment location can be found in Frame Clamps.
The DAESSY Rigid Mount – DRM1 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 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 tube to tighten bolts. It does not matter how the wheelchair frame tube is oriented because the Swivel Clamp allows the Frame Clamp Outer Piece 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.
Most often the best location for the Frame Clamp assembly will be near the front caster wheel but preferably not above it. The Vertical Tube for the mount protrudes down through the hole in the Frame Clamp Outer Piece and the range of height adjustment for the mount may be limited if the tube interferes with the caster wheel.

In most situations the Frame Clamp Inner Piece will be located forward or backward from the position for the mounted device and the Vertical Tube supported by the Frame Clamp Outer Piece will have an S-bend.
Obstructions
Obstructions directly above the selected location, such as the brake lever or other controls that are closer than 10 inches may interfere with insertion and removal of the Vertical Tube. To avoid this interference it may be necessary to use an Offset Link (O3L) or a Frame Clamp Spacer (UFCSPCR) between the Inner and Outer Pieces of the Frame Clamp to move the Outer Piece further out, or position it sideways from the location of the Inner Piece. More information on Frame Clamp Spacers and Offset Links can be found in Connecting Frame Clamp Inner and Outer Pieces.
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 DRM1 has the following steps:
- Selecting a Frame Clamp location
- Measuring and Specifying the Frame Clamp size
- Determining the Vertical Tube length and shape
