What type of bolt could be used to hold the bifold open?

WIAWSNB

Hi.

When only one 'swinging' bifold door is being used, how can it be held in a partially-open position to suit different weather. Obviously it will be blown open and closed if left swinging.

It has the magnetic bumpers to hold it in the fully open position - flat against the next door section - but there are many occasions when the user would like it partially open - one foot ajar, two, etc.

I was hoping that one of these foot-press type bolts would do,

but the gap between the bottom of the door frame to the decking is around 100mm, so that amount of 'throw' at least will be required, and I can't find one long enough.

Also there are swing-down stoppers, but I can't see them holding the door in gusts in both directions?

So, it looks as tho' a slip bolt may be needed, along with a number of receiving holes?

 

Or anyone got a bright idea?

You could try using a chock, sized for the gap.Would save drilling into doors and decking.

Thanks. But quite a big chock, and it would need to be reliable if left unattended for a bit.

Drilling into the door should be fine, if short self-tapers are used. A few round holes into the decking should be fine too - tho' thinking about it, it would make sense to drill right through to drain?

There’s a product called a stoppy that holds the door in any position.

I like that! Gap a bit too large, unfortunately.

Looks like a slip-bolt is has to be.

Thanks.

Or, has anyone had any experience of the swing-down type of stay? Do you think it would be strong enough to hold a half-open outside door?

What do you mean the gap is too large for a stoppy? We use them on our french doors - the stoppy goes in the small gap between the door and the frame, not the big gap you walk through. They work great.

So this door is one that is the first in the concertina of the bifold and moves along the track?  I think you'll struggle to find something ideal for this.  Personally I wouldn't be keen on a kick style lock, as it could place undue pressure of somebody standing on the open door if they catch the stay in the wrong way.  On my own bifolds, our access door is stand alone from the concertina, and I was able to add a fairly standard friction restrictor/stay to the top of the door, same as you'd find on standard french doors - this of course isn't suitable for a door that swings 180 degrees and slides up and down a track.

We have one on conservatory doors to let the cats come and go - they work absolutely perfectly at stopping the door closing. What they don't do is stop the door being blown open if a breeze catches it from the inside. I think the stoppy might have the same issue? 

We have a rather low-tech solution of a looped piece of string fixed behind the strike plate that goes around the door handle to stop it blowing open.

Yes, but it would require a series of them to suit differing opening positions. But if the user is happy with, say, just two positions, then it's a possibility. Thanks.

It slips under the opened door, yes? The gap this fellow has is around 100mm, alas.

Are they nicely secure? Would you use it happily on an outward opening door in stiff breeze?
