Item Description

Give yourself some peace of mind with the Mace Big Jammer Door Brace. It offers protection against forced entries with correct installation. Use it at home, in a dorm or an office. It's an excellent solution for bracing older, thinner doors or most any door that you want to shore up with extra security. Installation is simple whether you're handy or not. It works with sliding glass doors so it's just right for older glass patio doors that have a reputation for needing additional locking mechanisms. This home security door brace is also appropriate for hinged units and you can easily adjust it to fit most standard sized doors. Use it with any flooring, from hardwood to carpet. Strong 20 gauge steel ensures an uninvited person stays out. It also comes with a security bracing pin for added strength, ensuring that it can hold up to most intrusion attempts. Simply push this item under the door knob for added security. The Mace Big Jammer Door Brace features a collapsible design.

Customer Product Reviews

Rated 4.5 out of 5★ by 74reviewers.
Rated 4 out of 5★ by Mace Big Jammer Door I purchase this as an extra security measure for my daughter. Sometimes as parents, we are still concern for our children's safety. Although there are locks on her door, I just thought this would put my mind at ease. After seeing the product, I felt it was an excellent choice for what I felt she needed. She told me it works fine and, that it made her feel safe. 10/07/2013
Rated 4 out of 5★ by As expected Product arrived on time and in good shape. This Mace Big Jammer Door Brace is not a complete source of security though it will buy you some time (when properly installed) in case of forced entry, which why I purchased it. An added benefit is that it pushes the door against the weather stripping, giving it a tight seal providing a little more sound and weather proofing. 05/20/2012
Rated 5 out of 5★ by Door security bar I got this for a gift for my daughter who lives in an apartment, where you don't know who had keys or anything before and she feels more secure and can actually sleep at night. My wife has had one for years and takes it to motels or when we go anywhere out of town. She even uses mine on our bedroom door at home. With home invasions and break-ins I would recommend one of these for added security. 12/30/2012
Rated 4 out of 5★ by A little more piece of mind. Well-built and I believe it will do what it says it will on doors with solid locks and hinges. 03/12/2013

Rated 5 out of 5★ by Mace Big Jammer Door brace This device is very strong, adjusts to any regular door with knob, and can be compared to other door jammers that cost twice as much. 04/14/2011
Rated 5 out of 5★ by Great Security I live in an apartment after living in my own home for 35 years, it is a little different being where you can hear other people going in and out, this is absolutely what I needed and wanted, I also researched this and this was much less than all the other stores that I found the same item in. 12/06/2012
Rated 4 out of 5★ by Security assistance The Big Jammer, for the price, is well worth it. Adds door security, sturdy, is a value in that it adds peace of mind when you lock up at night, or even during the day. 02/04/2010
