Older model Jeeps have doors that are removable and hang on hinges and these doors can open wide enough to connect with the front side of the Jeep. To keep that from happening, 4WD offers door check straps. You'll find the traditional nylon strap from quality brands like Smittybilt, Warrior and Kentrol. There are also sturdier mechanical solutions with multiple stop positions including Billet Mechanical Door Stops from Armadillo Industries and Smart Door from Star Fabricating. Color choices are available to match your Jeep's interior (black, red, silver and stainless steel).
