4Bros Door Check

Our 3D-printed Door Check (sometimes referred to as a Door Stop or Door Jam) is designed to allow any user to keep any door from 1" to 2" thick open by way of friction applied from the flexible nature of the door. The Door Check will also work with thinner doors with a hinge accessible for Door Check placement.  Our Door Check is made from Red TPU or Thermoplastic Polyurethane, a flexible material that prints easily.  By definition, the material is resistant to oil, grease, and abrasion.  The elasticity lets it flex while keeping enough pressure on the door to hold itself in place. We choose Red material for visibility. The design incorporates a 1/4" hole in the top, perfect for adding a paracord or shock cord lanyard (not included).  This is a must-have for anyone who may need to make an entry on a door or make sure the door stays open while moving in and out.  These stops are handy when hauling the groceries in for the wife.  Please note:  we will only have a limited number of Door Checks available, and when they are out of stock, they will not be available for backorder. These are a fun adventure for us and will not be sold in a manner that impacts our holster order lead times.  Testing Results: We like to try and test the products we 3D print to failure. Although not "perfectly scientific", we apply real-world testing to each product before release. We have released a limited amount of door checks to local law enforcement and firefighters for testing and product improvement suggestions. We have yet to receive confirmation of any failures.  If you have product feedback or continuous improvement ideas, Contact Us .  We want to hear from you.  See all our Accessories, tools, etc. here: 4Bros Four Brothers Accessories
