It was time to replace the windows in our 41 year old house so we shopped around for a contractor. We chose a popular fellow who has a business here in town and has worked on numerous houses in our extended neigbourhood. An established professional in good standing -we had dealt with him previously when we needed new siding.
The window replacement included upgrading our heavy wood & glass sliding patio door for something with new bearings that would slide easier. We took great pains to point out to the fellow that this was my secondary wheelchair exit and that It was imperative that I should be able to get through it without restriction. He assured me I would.
The old door had a very low threshold allowing me to drive through the door opening with hardly a notice.
The new door was installed and right away I noticed a problem. There is a 3 inch (7.5cm) high threshold which now has to be mounted with my wheelchair wheels in order to begin the climb over it. Worse still is the fact that these new light doors are all made from some sort of extruded plastic which seems to delicate to be driven over by a 300 pound chair plus my own weight.
Where my old door's track and mechanism was made of solid wood and a stainless steel runner which was embedded at almost floor level, the new one rises 3 inches above floor level and is framed with flimsy, fragile plastic.
What is worse, I am scraping the sides of my armrests as I try to line up and maneuver through the opening. Kinda like threading the needle with a floppy thread - lining the two up takes repeat attempts and patience -not what you want if the house were on fire.
So, the explanation is this: Doors are made with flimsy materials because that is what makes them light and maneuverable, but mostly that's what makes them inexpensive for manufacture. Good for the manufacturer, not so much for the purchaser. Cheaper materials do not translate into an inexpensive product. Most major manufacturers produce comparable doors at that price. (not bottom of the line, either!)
The high threshold has something to do with local safety standards. I cannot see what a three inch threshold protects you from - in fact it is a tripping hazard! It certainly won't keep out any floods. Anyone think of some other safety issue the three inch threshold would protect you from?
Yes, the specs show that the doors opening is certainly wide enough for my wheelchair. But that is before you add the safety stops which prevent the door from falling out as well as the door handle which acts somewhat like a bumper, not allowing the door to open to the maximum. Together, these reduce the doors width by over three inches, leaving only 1/2 of an inch on either side for me to squeeze through.
So, I've adjusted what I could to maximize the width without having the
door fall out of the frame. I will take my time and try not to break
the door frame whenever I attempt to use the door.
I considered buying
commercial ramps to scale the height of the threshold. Some are dense
rubber of various 'rise over run' dimensions. They cost about one
hundred dollars each and I would need one on either side. While these
commercial ramps solve the height issue, I still have a 6 1/2 inch (16
1/2 cm) transition gap between the front of the threshold trim and the
rear of the threshold trim. I cannot simply drive across this divide as
the plastic is too fragile and would no doubt shatter. The aluminum
runner on which the door glides is also of thin gauge metal and would
quickly become bent and misshapen after only a few passes. A helpful
neighbour built a small metal ramp which I can lay down to scale the
transition. It has a wooden crosspiece which lies in the central
plastic channel thereby distributing the weight to protect the sides and
I am grateful for this ramp but it still has to be lined up carefully so that when dropped in, the cross brace enters the plastic channel to distribute the weight evenly. While I am flexible enough to do this myself, it may take several attempts to get it in properly. I then carefully 'thread' my way through hoping not to damage my chair or the door jamb. Once on the other side, I have to pick the ramp up in order to close the door behind me, so as to keep the insects out.
Not as quick as before when I could just open the door and drive on through with ease. But, it is what it is....
Even when you ask the right questions and get assurances, things may not work out as you expect!
It consists of (1.) the door frame base, (2) the plastic wall (2 pieces) which sandwich (3.) the aluminum runner on which the door rolls or glides. (4.) is the channel through which the front face of the door runs through which I fill with the ramp's cross brace to reinforce against crushing. (5.) is the outside plastic trim behind which the door face runs as it slides open or closed. (6.) is the screen door which runs on its own, lower track.
