FloPlast Miniflo Black Half round Union Bracket (Dia)76mm

Generally the guttering was fine but the retaining clip on the union joint broke off when I was fixing it on with hardly any pressure

Both clips broke off when trying to fit. With replacement I will cut a little off the gutter - but aware this may result in leakage....

Bought some Miniflo guttering for my shed but so far all the clips on the Union Brackets have snapped - and it is 20 deg outside! When I returned them to B&Q (what a nuisance) I noticed some more broken ones in the stock pile. Clearly these are made from cheap plastic that is not flexible enough for the job.

Whilst these 76mm fittings are generally good quality there's one major problem and 1 thing to look out for:

Major problem - there's a "dial" mark showing manufacture date right under one of the black sealing strips. This caused my fittings to leak until I put a bead of sealant under the black strip.

Thing to watch out for - these "joiner" pieces have their fixing hole at a slightly different height to the thin support clips. I found the fixing hole of these joiner pieces needed to be 2mm higher than the thin support clips. This is a significant distance when the gutter is sloping at a shallow 1:300 - 1:350 angle.

This bracket had to be replaced in store due to the breakage of one of the tiny lugs that keep it attached to the gutter. Considerable force is required to "latch" it to the guttering and the lugs are too flimsy to withstand this in every instance.
