How to fix anchors too loose in brick wall?

[CassM]

 

Hi, I tried to install a Daytek clothesline onto my brick wall using the Dynabolts suggested but even though I drilled 8mm holes for 8mm bolts the anchors are loose and are being pulled out by the weight of the clothesline. 

My brother in law suggested using Ankabolts and they do look easier but the 8mm ones are too wide to fit through the mounting brackets. 6mm ones fit but are obviously too narrow for the drilled holes. Is there something I can use to make the 6mm bolts fit in 8mm holes? 

Thanks for your help!

The Ramset 3/16" x 100mm Round Head Spring Toggle that @R4addZ mentioned comes with a 100mm bolt, and I am not aware of any longer 3/16" bolts that could be used to extend it further. I'm not sure whether, with your depth of 75mm panel and the thickness of the mounting bracket, the spring mechanism will be able to expand behind the panel.

Hi Guys

@ajperry I would drill through the wall carefully noting when you lose resistance as this will give you an idea where the cavity begins (make sure you don't end up drilling through to the interior) then stop the drill and push it in till you hit the interior wall, the difference between the two will be the space you have in the cavity it will also tell you how long a thread you will need and that is the width of the outer wall plus the length of the spring toggle when closed plus the depth of the bracket plus about 10mm to make sure you can get the toggle to open. The reason I suggest sleeving the screw is due to the movement, the thread will be considerably thinner than the hole and it would be advisable to reduce the opportunity for the thread to flex around in the hole, might I suggest offcuts of plastic plugs but that is just a thought. Once you know the length of thread needed, you will need to buy replacement screws for the ones that came with the toggles (you may be able to buy toggles with shorter screws to save cost but don't do so at the cost of thread diameter),

@MitchellMc , There are specific fixings for dynamic loads and most people don't realise this. In a previous life (back in the UK I worked for a company called Spit fixings (Special Products For Industrial Techniques) who were a french owned competitor to Hilti, I was in sales and also had such jobs as teaching customers how to use explosive power tools safely (the reason I eventually left the job as a customer who was trained by a colleague had an accident and he was blamed, I didn't want the same thing happening to me!) Anyway, I digress. Usually the dynamic load anchors are self drill anchors and in setting these anchors they create a cone shaped hole with the base of the cone on the inside. It is this cone shape that makes it capable of taking dynamic loads as other anchors which are inserted into a straight sided hole rely on outward pressure and they will "walk" out of the hole. And then there are chemical anchors!

Thanks! And thanks to everyone that has helped. 

I’ve noticed that there are toggle bolts called SnapToggles. Bunnings seems to have a product similar to these - Cobra I think. 

Anyway I’ll have a look and see what the dimensions I have to play with are and whether Ramset has a solution, or I need to consider another solution. 

It may turn out I get Ramset for the spring and then extra long screw/bolt and washers. Cobra seem to be limited to 60mm depth, where I need at least 75mm for the Hebel. Behind the hebel the space is the wooden frame, plus 25mm (which accounts for the top hat). So plenty of space for a toggle to expand.

Hi @ajperry,

I've just been made aware that we are now providing a Hose Reel Installation Service. So, if you or anyone else reading the discussion continues to have issues, you might like to take advantage of it.

Thanks Mitchell,

I read the fine print. The service excludes Hebel walls. 

I was about to order it too. 

Pity.

I have noticed this video - https://www.tiktok.com/@rosiesrustics/video/7393562027253419295?is_from_webapp=1&sender_device=pc

This concept was described earlier along the lines of concreting in a post and attaching the reel to the post. As I have a concrete path, would bolting a post holder onto the path using expander bolts and then either a wooden or metal post into that holder provide a strong enough mount? it will add a couple of inches to the reel jutting out from the wall, but might be better than pulling the Hebel out in sections over time...

Thoughts?

Hello @ajperry 

Mounting the clothesline onto the concrete path is definitely an option. Just letting you know that Daytek has a mounting kit -  Daytek Anthracite Black Ground Mount Kit With Base (please double check size and compatibility with your clothesline model). It's also possible to use timber and a post anchor for the concrete path. Personally, I find this option easier rather than drilling into brick, Hebel or aerated blocks.

If you have any other questions we can help with, please let us know.

Hi Eric,

I'm looking to reattach a hose reel to a Hebel wall...not a clothes line to the ground. But thanks for the advice.

My last question was whether I could use a post kit of sorts and either a wooden or metal pole. The issue I have had is the recommended fixtures are pulling out of the wall...twice now. So doing the same thing is just going to result in the same outcome. Either I use a fixture that sets against the rear of the Hebel, like a toggle bolt of sorts, or I fix to the ground. I can't really dig a hole and concrete in a pole as the house has a concrete path all the way around.

Have a read of the all the messages leading up to the last one and you might better understand the issues.

Hello @ajperry 

My apologies for the miscommunication. I'm sorry but there are no garden hose reel post kits available at the store. However, you do have the option of using standard fencing posts such as the 90x90 or 100 x 100 x 2400mm. There are a number of anchor post's available, and it all depends on your preferences. Using Dynabolts or AnkaScrews will work with the anchor post when installed onto the concrete slab.
