MRO Logo
Effective January 2, 2020 MRO Electronic Supply Ltd will be wholesale only.

MRO Electronic Supply Ltd is extremely proud to be a top tier supplier in North America. Today our custom cable manufacturing business is vibrant and growing. Because our market for custom cable manufacturing is expanding rapidly, a transformation within the retail segment of our business has become necessary.

Due to market forces and an ever changing business environment MRO can no longer support the retail side of our business. The current space will still remain open and available to our wholesale customers, but will not be open to the general public. We would like to thank you for your business and your understanding regarding this decision.
