Advice on installing frame anchors in PVCU doors please.

I'm about to install some PVCU (plastic) French doors from Wickes and
I'm not sure about how to go about installing the frame anchors.

The anchors are 8mm diameter so I need to make an 8mm hole through the
door frame to accommodate them. The problem is that the hole will go
through the steel frame inside the plastic frame as well and I'm not
sure whether I should start with an 8mm HSS bit and just try to make
the hole in one go, or would it be better to use a pilot HSS bit of
smaller diameter first to stop the larger 8mm bit wandering?

Anyone have any experience of doing this? What should I do?

Thanks for any advice.

Having drilled hundreds of thousands of holes through anything that can
be drilled, by hand with a power tool, I would put in pilot holes first.
Start off with 2.5mm and increase to 5mm. The 8mm drill will follow
these holes ready for your masonry drill to follow into the wall. Just
be gentle and ensure that you don't put the pressure on the drill from
the pistol grip, but just use the handle to access the switch and put
lots of pressure on the back of the drill. Just make sure the drills are
sharp. If you had started with an 8mm drill, who knows where the hole
will end up in the frame. You can grind a drill, can't you?

Those anchors are more usually used for timber doors. I have seen the
blue screw that go directly into the masonary used, much smaller hole
required.

Fitting plastic double doors is a PITA. They have to be dead on or the
locks won't work properly. You will need plastic packers and need to
ensure the frame is vertical. square, parallel etc. in all directions.
The problem is the frame distorts so easily when you tighten up the
fixing screws. The bigger the door, the worse it is. You need the
packers with a slot that goes round the fixing screws.

The glass in the doors needs to be tighly wedged with packers to
prevent the doors distorting too or they won't close. There are
special packers for this purpose.
The hinges and locks have a multiplicity of adjustments too.
Best of luck.

Bosch multimaterial bit straight through the lot works quite well IME.
(it may not be long enough to drill the full depth in the masonry - but
it will serve to start the hole off if nothing else.


Use packers to keep everything square, keep testing as you tighten
things up. Once its all sat square you can foam it in place. You don't
need that many frame anchors in total - say three per side and depending
on width one or two along top and possibly bottom.

Remember the opening bits derive much of their rigidity from the way the
glass is fitted. You want the plastic packers to brace the glass in the
rebate so that it acts like a restraint to the door drooping.
