When you need a replacement sector block for Invacare power chairs & wheelchairs, you can try your luck with a roll of duct-tape, or you can get the real deal from Monster Scooter Parts. Available in either the left side or the right side configuration (they aren't interchangeable), these are the sector blocks that Invacare uses on a number of their wheelchair and power chair models. Please refer to the Compatibility list to see if these are the correct items for your model.
