Recognizing our clients needs to offer modern required products in this ever-changing marketplace, we began searching premium manufacturers that could provide quality products that met or exceeded our high standards, specifications, and requirements for different market segments here in the US.


At 3-D, the best quality product lines with the label “MADE in the USA” is what we are known for. So, naturally, if we must source outside of the United States for additional products that are not provided domestically, we would look to source from a Company and a Country equally matched in quality and care.

After extensive research, we united a perfect match. 3-D Lockdown Supply + Remsafe Window Locks equal Keyed Window Lock Security (WOCD) that are now available in the USA.

We are proud to say we can provide YOU, the United States of America, our new line of window security products, designed in Australia, and distributed Coast to Coast through 3-D Lockdown Supply, LLC.   We are your source for Remsafe Window Locks in the USA.
