Do you have room to use interlocking duct bank spacers?
Is there a product simular to Cully "Quick Caps" for larger pipes? They are used for spacing with slab work and cement.
where do you get those, and how expensive are they?
i need about 300 of them for a slab i'm doing in a couple
weeks.....
i googled them, and nothing much comes up... i've
not seen them on the left coast....
thanks
