Coroplast

[Ddubya]

Had a slide hydraulic ram fail and fluid everywhere. I need to replace some of the coroplex. Does anyone know a source for a 4x8 sheet of 6mm (1/4 in)?

Often times print shops will have it on hand. They use it to print real estate signs, political signs, etc.

I found a local plastics shop that ordered for me for about $11 a sheet.
Google is your friend.

I bought a sheet from local HomeDepot....

I found it at a wholesale plastics company (Allied Plastics) $14.00 for a 4x8 sheet (black) minimum order two sheets. By the way,I measured mine and it is 4mm not 6mm.
