[FASTSIGNS]

Hi all, looking for a suggestion for a nelson harkins type company for replacement directory strips (reverse engraved- black out). TIA

post pic please and if Im thinking these are what they are I dont see why you couldnt reproduce in house using thin clear poly and black vinyl

if they are what i used to make for another sign company, it was the acrylic clear strips that had reverse weeded black vinyl on it? the acrylic was frosted so you would not see the lighting in the directory. the strips were 1.25" tall by 27" long and i had to cut the offsets so they would lock together.
