sorry for being thick but i am sue someone can offer me some advice.
i have a bay window which has half round pvc gutter with two angled
returns and a down pipe. the anles need replacing as they are leaking.
on going to b&q and purchasing 112mm size angle i thought this would be
ok. the angles will not fit the gutter, there is only a small differance
of around 4mm ish. i dont really want to replace the whole lot. the
markings on my anle are 100 x 135. has thier been any standardisation
in past few years maybe.
many thanks in anticipation.
