UPVC door/window beads - hammer?

[james36]

Looking to but a little Thor hammer for knocking in UPVC window beads and I see they do two different sizes, both with removable nylon faces. Basic difference is one has 32mm faces and the other has 38mm (and is a bit heavier).
Anyone use one and if so what size for beads? Nobody near me seems to sell them so I can't have a look.... so it's an online purchae
Cheers.

I use the smaller one, plenty enough for pvc beads

I use the heavier one - bit more weight when youre working in a tight reveal. Don't get the one with the red faces, they can mark the bead after they get worn.
