Plastic wall plug alternatives

Hi all, 


Just wondering what people are using instead of the good old fashioned plastic wall plug? I’ve got a run of swa to pull in and am looking for something to meet the new regs. 


Ive seen the dewalt wall dog screws but have seen mixed reviews about them. 


Thanks

    I recently used DeWalt wall dogs to secure fire-rated black P clips  made by SWA.   https://www.swaonline.co.uk/fire-safety-product-range/firefly-cleats

    The combination worked well for fixing 4mm SWA into breeze block  crossing over a garage door entrance about 5 metres wide.

    Regards,

    Mike.




    The cable will only need a centre fixing and one at each end to prevent "premature collapse" so a steel wire wrapped around the S.W.A. and secured to a screw or cup hook at those three points will do the job.

  • But look awful.

    The idea of only using fire rated supports at strategic points has its merits and one that I considered.

    However, if you are going to the expense of three screws, three wall plugs, three bits of wire and three cup hooks(say 50p), then why not go the extra 50p and splashout on three p clips and three wall dogs?

    I’ve never come across things falling off walls due to the rawlplugs melting in a fire and I’ve been many fires.


     




    So were you a firefigher or an arsonist in a former life??? :-)

    And we would've been well out of the building by the time the plaster/walls started to collapse.

    Yeah but the point is to stop cables faliing before the plaster/walls start to collapse.

    As I said, I've never seen or heard of  plastic rawlplugs melting and therefore letting cables start falling, especially before the plaster starts to fail, bricks have to get extremely hot (takes a long time to do so) before their structure starts to fail, 9 times out of 10, civilians and firefighters are well out of the way if/when this happens.  Unlike what they show you in the movies and on tv, wall collapses are quite rare.




     

  • A bit late to the 'party' but as an expedient before common practice establishes itself, I've found that a suitable number of 2.5mm solid copper strands works in lieu of a plug in sufficiently strong masonry/concrete. Mortar is more of a mixed bag but is with plastic plugs also. The copper is ductile enough to take the screw thread, and if using a tapered thread screw, you get a fixing that's at least as strong as a normal plug, probably a lot more.  And isn't going to melt. Also, as an electrician, such a material is readily available.

    [edit: the occasion we used this was to fix 'firefly' fittings inside minitrunking every 2nd fixing, prior to the 18th but over an escape route.  The building inspector was happy and seemed pleased we even KNEW about the regulation]
