Security Devices International Inc.

Sales will be through the global UTS network of more than 6,000 customers across military, law enforcement and correctional services agencies. The TLSA includes an initial Standing Offer from UTS for US$500,000 as a contracting vehicle for volume purchases, with related provisions that guarantee minimum annual quantity purchases. The TLSA also provides SDI with access to the UTS training network of more than 100 less-lethal trainers for end-user certification on SDI products within these agencies.
