This clear Safco acrylic collection box is designed for suggestions, ballots, entry slips, payments or forms in offices, schools, events and customer-facing spaces. The back panel slides out for easy access, and the lock with two keys helps protect contents until collection. A 5-3/4 x 1/2 in. top slot supports common forms and cards. The tall 9-1/4 x 9-1/4 x 21 in. format makes it visible on counters or display areas.
