Which dowels do I need to wall mount my pull-up bar?

Hello,

I have the following pull-up bar: https://www.amazon.de/Klimmzugstange-Wandmontage-rutschfesten-verschiedenen-Griffpositionen/dp/B09FQ814L7/ref=mp_s_a_1_1_sspa?crid=8LKY4ZZEKM5T&dib=eyJ2IjoiMSJ9.SOn0XAw-6OCbVRp5DjBd5Z5rmiht8qlULPZBxrYWBPEc_dN1_TZYNL3g_jRGEx0qiU01bPRcLr35vR3FPWwfs3o6be06AFvP9L4mqLgdYHaesNlyFjly-H_mM_oAYd-yivue4Ytid4l IwtXvCSpCAhhe-HgCVMwFZtIcvNfhdRJXNZOCGGOgqjEH20R4nbcyadwFgnfYSQazK6BQ5QPY0Q.BLNPFrs_q3ff6LVN9Y6xvK_JC-ox_rt689TLlQvUHPI&dib_tag=se&keywords=klimmzugstange+wand&nsdOptOutParam=true&qid=1734617612&sprefix=klimmzugstange+wand%2Caps%2C190&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfYXRm&psc=1

If I see it correctly, there are eight 14mm dowels and screws included. My problem is that I might not be able to drill deep enough into the wall, and I'm wondering if smaller (10mm?) dowels would be sufficient. The wall is solid, but I'm not sure what material it's made of.

I'm not sure how to interpret the information regarding the maximum load (300 kg). I suspect that doesn't refer to the dynamic load. I guess I lack the technical knowledge here. I think if small Fischer Duo anchors can withstand 30-40 kg, then eight giant anchors should be able to withstand well over 300 kg (dynamic load), right? I'm happy to be proven wrong. (And of course, the 14 mm anchors are not Fischer Duo Power anchors or similar.)

I weigh 85 kg, and as far as I know, the dynamic load during pull-ups can be three times my body weight. Hence the question: are 10 mm dowels (or even smaller?) sufficient?

Please only factual, constructive contributions. I don't have any use for smart-ass comments and won't hesitate to report them. After all, I'm here because I don't have the answer. Thank you for your attention and help!

8’s dowel means 6’s screws that are too small. In a concrete wall, 12 dowels would be enough. In a walled wall not all dowels sit centrally in a stone, but also partly in or next to a joint. The dowels have to sit in the material with their entire length, the cleaning layer does not count. And this will give you the length of the rubbish. A wall is at least 12.5 cm thick, that should be enough. If she’s thinner, she won’t hold the tie rod.

The load capacity of the dowel depends heavily on the wall. 8 He should be enough dowels, but they must sink deep enough into the wall. Otherwise, the strongest dowel is powerless.

Thanks for the answer! The next question would be if I find screws with 8 plugs whose head is large enough to clamp the rod to the wall. 8’s dowel means 6’s screws, right? Thanks again!

(Question to be sure about the walls soon.)

Yes 6 he screws but not smaller

The head shape of the screw does not matter if you are using washers. They also distribute the pressure better

I made discs in things where the load was uncritical. Maybe I think it’s more complicated than it is. But then the screw may not go as far as it needs. A few mm take the discs.

Thank you for the contributions! 🙂
