Mounting 4" Foam Letters backed with PVC or wood to a truss

[Andrew Hodgson]

I have a client asking me to make 4" thick letters. It's a smaller budget, so my plan is to cut 4" foam and apply either 3mm PVC or a thin sheet of wood to the back of the letters. The client thinks they can just Velcro the letters to the truss. I am worried that they would fall during the event. How would you recommend mounting letters to a truss?

Thanks for the quick reply. Can you let me know what Door skin backing is? I am not familiar with this product.

I cut letters like that all the time for a trade show company they laminate with P lam and the I cut them. They use vecro to hold them up so they can take them down without damage for the next show

Home Depot carries door skin. Thin 1/8” thick interior wood not expensive

Door skin = Lauan Plywood. I would have nothing to do with velcro attaching letters to a truss for an event.
