Door Opening Restrictors

Post by John042 » Wed Jun 03, 2020 11:16 am

Hi. Has anyone found a solution to the door opening retaining mechanism which fits to the bottom of the doors and is usually rotted out? I was considering a simple strap retainer to restrict the door openng. Thanks for any ideas. J C.

I bought a new restrictor/strap for my GTC, it must be (ahem) 5 years ago. I spoke to a good friend whose business is "composite" (we don't say plastic, GRP or even carbon fibre these days) fabrication and repair. "No problem", quoth he. "I can just cut along the bottom and inside of the door, break out the broken bit and then re-glue the new one in before sticking it all back together for respray". The part is still in the bottom of my bits and bobs box ....

The restrictor is held to the bottom of the door with just Two bolts, never cut the door apart but there must be a steel plate bonded in.
I have a few in VGC. Door check straps that is :lol: but I also have tons of the rust here ATM

That's right. It's the steel/rust plate bonded in which causes the problem - and major surgery IIRC! If you know of a simpler solution, please let me know. I have the time - now I'm retired!!

I suppose in theory a SS tapped plate that sits INSIDE the door, much like the SS hinge support plates I used to make. :idea:
The Two bolts that hold the unit in place go all the way through and have a flat and spring washer to keep the nuts tight. :roll:
A larger area to take the strain would help too. :lol:

Do you know, Mark, this is starting to motivate me! I'll get son James to start scrabbling around under the door to have a closer look, and have another look inside myself. I seem to remember that I filed the whole project away under "Too much trouble" at the time. Ever since then my wife has complained about the unrestrained door trapping her legs every time she gets in or out! Sorry to hijack your thread JC, but this could be useful to you. A check-strap alone will protect the bodywork, but not help your passenger!

Not at all Philip. More ideas/solutions the better. What happened to the good old leather straps to prevent the door swinging open? Simplex I agree and not much help stopping the door suddenly closing.

just to add to the confusion, I found that the bottom/inner plate for the restrictor, if its an original, is welded to the door stiffener. So to remove it may mean a full strip down of the inside of the door and if the bottom plate has rusted away then proberly the door stiffener has as well. I do know Nige has some useable parts but the replacement is not an eaay task. That said it is well worth doing as failing to do so will most likely result the doors dropping and cracks in the fiberglass where the hinges clamp to the door. you may also find that the bottom of the window frames has rust issues as well. I hope this helps you decide what is best to do and if its of interest I do have some pics of what to expect.
