Door panel security bars are recommended to increase security. DoorGuard Bars are not expensive, do not have to be measured in advance and can be purchased and fitted extremely quickly. They are very easy to fit with 3 zinc plated hardened steel woodscrews supplied with each single bar. They will fit the width of most doors without alteration and provides instant security and can be positioned to allow access glass cleaning. The bars are recommended for internal fixing. If they are used externally, we suggest that security screws or fixings are used.
