50mm wall screw with “Universal” wall plug
These plugs are very good and usually work where conventional wallplugs won’t tighten due to the brickwork having voids in it or being particularly soft. The plugs also work in solid masonry, obviously.
Requires 10mm hole.
See article on wall anchors, and remember more wall anchors = a stronger install…..
Note that four anchors are required for a standard wall bracket and five (or more) for a pair of T & Ks.
For heavy duty fixings see sleeve anchors.
P&P is cheaper for this item if you phone the order through !
