Cavity closers

Can't see anything either way in the reviews, can you use both sides of a product like this if you cut it at 50mm?

I doubt it as you need the plastic part to overhang both walls , so there is only enough for 1  closer at 50mm. The offcut would be short on one wall.

Thanks - so just cutting the excess away then and have more plastic to lap the blockwork?

Not sure it’d  work if you cut it in half and then cut back insulation you’ll have less than 50mm on each piece? What’s your cavity size? I think once piece is designed for up to 100mm, not to be cut in half to do 2x 50mm
