    Hi,

    Looking for help locating something along this lines. It's a part to screw into the door frame to hold a pull up bar. Needs to be 30mm across.

    Have tried the local hardware store but no luck. Can find one seller online but €9 seems a bit steep given I can buy them plus the actual pull up bar for twice the price.

    If anyone knows where I would find them for a reasonable price that'd be great. Or even what they're called...

    I wouldn't put a pull up bar out of that ever. Screws are not meant for torsion strength they are for tension. Meaning they can snap under duress if force is downwards in the direction you want to fit them.


    Go buy a new bar the ones that fit between the door frame and lean on the wall above . Much safer built for purposes and very cheap too.

    I had one of the over the door frames but it's was very bulky and meant I couldn't close the door either.

    Might be wrong but it'd be tension, not torsion surely? The bar sits inside the cup just. I had one before and it was grand.

    I also only weigh 70kg so it's not a very heavy weight going on it.

    Torsion, as you would be bending down on the screws not trying to pull them out.

    Its one of the reasons Nails are the preferred mode of building Timber Frame walls rather than screws.

    Hmm...I'm not too worried tbh. It worked fine for me before.

    Other option would be something like this but would involve drilling into the wall. I also like the idea of one in the frame so that it reminds me to do a few pull ups everytime I walk under it.

    It's not torsion as you're not twisting them (only when you're screwing them in). It's shear

    Maybe I'm missing something very obvious here, but when you've put the caps on either side of the door frame, how are you going to get the bar in? :)

    In Cavan there was a great fire / Judge McCarthy was sent to inquire / It would be a shame / If the nuns were to blame / So it had to be caused by a wire.

    It's extendable. You twist it round to fit in place.
