Each of these Protex 61-1610 type fasteners is screw-adjustable in length from 88 to 98mm and weighs just 80g, yet has a thoroughly impressive breaking strength of 450 kgf (4.41 kN).
That applies equally to versions in mild steel (with a yellow iridescent, zinc plate passivate, protective finish) or in stainless.
The Protex device features a mating catchplate and handy safety catch, operable by thumb, to avoid accidental opening.
The battery of the Stairmatic can move people weighing as much as a hefty 20st (128kg) up and down stairs, with a maximum of 1000 steps 27cm high per charge.
Two mechanically independent brakes lock the machine safely on the front of each step.
The accompanying charger plugs directly into the front of the wheelchair and is powered from any standard 13A socket.
The four Protex fasteners hold the assembly together, facilitate dismantling for transportation and ensure that access to the battery is both quick and easy.
The wheelchair is made in various models and custom designs (with side panels, soft backs, pommel seats, head and foot rests, etc), so that the justifiable claim of Baronmead sales manager Graham White is: "If you can't fit the chair, we make it fit you." Typical applications cope with steps and stairs in nursing and residential homes, hospitals, town halls, schools and colleges, theatres, hotels, pubs, clubs, ambulances and minibuses, with exports to the European Continent a steadily increasing part of turnover.
Units are serviced on site every six months by a Baronmead engineer.
