Review on 🚪 High-Grade Security Door Bar Set (2 Pack) with Kick-Proof Iron Design - 350lbs of Force - Ideal for Home, Hotel & Apartment Security - Adjustable Sliding Door & Patio Door Lock by Jeff Johnson

Very strong, reliable and easy to use. Combine all 4 pieces to hold the door closed with an oddly tall knob. Make sure the bottom isn't too close to the bottom of the door as this can stress the door handle and potentially break the handle instead of protecting you. Likewise, the bottom of the securityman must not be too far from the bottom of the door. Then he would slip out of the way easily. Drive it firmly into the ground with a boot heel, hammer, etc. Dusty, dirty, or slippery floors can also render it ineffective. Too much paint has flaked off after 10 days of continuous use, but I can't complain about the solid workmanship and the low price.
