Primarily Metalite are manufacturers of anything to do with disability support aids and mobility equipment and although Metalite have ceased manufacturing wheelchairs they continue to service, repair and customise equipment.
After being in the disability support aid and mobility equipment business for such a length of time, their workshop is a
maze of machines and spare parts.
So, if it's anything to do with wheelchairs, mobility scooters, or anything else in those lines Metalite are likely to have the part you need!
