WANYIAir Wedge Up Bag TPU Fabric Air Wedge Pump Kits, Professional Pump Wedge Airbag, Inflatable Pump Bag Alignment Tool for Door Window Installation and Car Repair with 1Pcs Door wedge (2SR)

Having previous used wedges of cardboard to prop a door up for re-hanging I have to say these make the job so much easier. I've tested both bags, the first I used to support a solid wood with glass panels so was a heavy, while I removed it from the frame for sanding and painting, the other bag I tested to lift the door for re-hanging and both bags worked without fault.The pump has a screw down valve which you unscrew to release the pressure. I used my foot to pump up the bag while I supported with my hands. The bags feel like they wont easily puncture and the seams have been embossed all the way around to ensure completely sealed and even under heavy pressure they held up fine. Also included is a flat and curved wedge which is also handy. Overall they have worked well and it will now be so much quicker to renovate all the other doors in the house.
