To compliment our product line North American manufactures and sells various accessory products. Some of these products are available for purchase online. We have several styles and sizes of SDT series deal trays and MDT series deal trays. We have recently introduced the MDTSC deal tray that includes a sliding stainless steel cover. NABP also suggests the use of an NASD-6 passive voice speaker device that is UL Listed to level 3 and also available in rifle protection. In the event a passive speaking device is not appropriate we can outfit your system with an electronic device made by either Norcon or Haven.
