These are universal, "tuckable" IWB struts. They allow you to carry your firearm (or other device) inside-the-waistband, while making it possible to wear your shirt in a tucked position. They are designed by NSR Tactical and made from a proprietary polymer material. They've undergone rigorous testing and are virtually indestructible.
This model is the pre-drilled 1.5cm variant. It features (3) IWB Loop mounting holes (with retention dimples) that are spaced at .375 inches and (3) lower mounting holes which are pre-drilled at 1.5cm spacing. The dimple feature minimizes loop rotation once the assembly is tightened. The standard 5 degree cant helps keep the mounted item pushed against the body. This is especially important for firearm mounts.
