Advice with fitting a sign tray
hi all,
finally received an order I placed 3 weeks ago (meant to be next day!!!)
anyway I ordered 2 x alu sign trays 810mm x 1200mm and these were meant to be with all fixings!!
they arrived and the sign trays look great however all that came with them is 4 x angles of aluminum which are 1200mm long.
Don’t normally get involved with this type of stuff but didn’t want to say no, any ideas/suggestions as to the best way to fix these to a brick wall (low level) also what fixings to use?
sorry for all this but the client is understandably pi55ed off now and I need to get this fitted pronto!!!
cheers

Graeme,
the angles go top and bottom of the tray internally. leave about 5mm clearance for the internal measurment of the tray, Fix the angles with rawlplugs and screws. then drill a couple of holes in the top and bottom of the tray, place over the angles and secure with self tappers (or self dril and tap if you have them
Use a screw cap (like on number plates) to finish the job.

Graeme, Peter has pretty much said it all, couple of things maybe different though. Before you drill and fit the top rail just make sure the bottom rail is not going to end up along a line of mortar and instead of self tappers I would use rivets, if it is low level and you don’t want people to see the rivet heads you can always cover them with a couple of vinyl circles. I normally use countersunk rivets so they are flush with the tray.

peter many thanks, my old boy was round there (hes pretty switched on with this kind of thing) and he suggested fitting timber batons (same width as trays) to the wall, top and bottom and then using self tappers into the sign tray and timber?
would this be an option too?
cheers
graemeps: my dad is helping me out on this anyway, for some reason he loves installation type DIY jobs!!!

Graeme, you could fit timber batons but the right angled ally is for top and bottom rails so why spend more money on timber
-
true martin, my dad just felt the fixings would take better to timber.
We have plenty odds and ends to use up anyway.
Ill speak to him about it tonight… off to watch the pool win the cup (drink1)
many thanks

If you are going to use self tappers then the ally shouldn’t be a problem at all as this is how they are normally done. If you are going to use timber just make sure it is not warped at all or you could pull the trays out of shape a bit. I would also make sure you use treated timber so it doesn’t rot as fast :lol1:

Never done one of these before. I can see the reasoning for 5mm clearance, but when the rivets/screws pull the tray tight to the angles would this not distort the 90degree angle of the return or is it that minimal that it doesn’t really show. 😕

Alistair,
Simple reason, if like Graeme you havnt done one before, the 5mm is to allow for a bit of error over the 1200mm.
The tray should be strong enough in the corners to pull the angle to it rather than the other way round, but in practice the screws are only tightened enough to bite makes fitting easier, better than being no clearance, and the tray dosnt fit….top screws tight, bottom just biting

I like aluminium trays and always use aluminium angle iron and sometimes flat cut aluminium lengths to keep seperated distance correct…….even just using the thin red tessa tape to keep it all together until it’s in position 😀

1. Drill 3, 4mm, holes down the 1200mm return (100mm in from each end and central).
2. Drill 4 holes down one side of the fixing angle, roughly equal spacings.
3. Decide where you are fixing the sign and using a spirit level, line the angle on the wall and mark off the holes that are in it.
4. Drill and plug the wall then fix the angle.
5. Measure from the outside of the fixed angle and repeat 2,3 and 4. Your tray is 810mm. If it’s made of 3mm aluminium then measure 800mm. This allows for the thickness of your material (X2) and allows a few mm clearance.
6. Place your tray over the angle and drill through the existing holes and through the angle using a 3mm drill bit.
7. Fix using 1"x8g screws.
