KM strap on grills

[UKBall]

I'm thinking of buying a KM strap for my vforce grills and i have no idea how i would install it. Is there a proper way of doing this?

for my grills i use km straps . You have to cut the old strap off and sort of just force the new straps in and the stay there its better with two straps. Mine have never popped out as the km straps are designed to fit the majority of masks.
