Our light duty step stakes are 30" high and work well with signs sized 18"x24" or smaller that are made out of corrugated plastic. Signs intended for use with step stakes must be at least 12" wide.  We recommend the light duty stakes for very temporary signage only.  If you plan for longer use, our heavy duty step stakes are a more appropriate choice.  If you order a sign from us that you intend to use with step stakes, please indicate that on your order.  The signs must be made with the flutes of the corrugated plastic alligned vertically so that the step stakes may slide into the sign.
