Joist end repair and splicing plates
all, quick E Mail just
to say thanks - brilliant product, the Bower Beams saved me so much work
it is untrue!! Easy to fit and work perfectly, I know they are quite simple
as a concept, but so often you buy workarounds and they just prove to
be a waste of time. Absolutely would use you again and will recommend
to a builder friend as this was such a positive experience and easy job
for me to do on my own as a DIY fix. I did it over two lazy, coffee fueled
mornings (4 joists) but reckon I could have done it in one morning if
I'd been bothered.
Thanks to all and take care. Samna.

Shown below - BM6 next to a 9 inch (225mm) deep timber. Normally a BM17 would be used for this size.
Note - coach screws supplied with the kit require pilot holes to be drilled, to avoid splitting the wood.
Joist End Repair Plates - fixed with coach screws using a socket wrench.
These steel plate BM Kits can also be used as splices to join on a new piece of joist - ask for double the number of Coach Screws, plus two Bolt Sets for extra security.
When working above ceilings the plates can be reversed so that the flanges rest on the ceiling itself, to avoid opening up and having to rebate the underneath of the joists.
Don't forget to treat all cut ends of just using our Boron Ultra Gel 20% to prevent future rot and insect attack.
We can provide joists machined to match the old Imperial sizes - modern joists are Metric and will not be suitable for plate splicing due to being thinner than the originals.
