What is a Rigid Stop? A rigid door stop is a common style that screws directly into the trim of the wall and has a rubber tip at the end (this will prevent damage to the door itself). This style of door knob is great for protecting the walls but will not hold the door open. Choosing a solid brass door stop (not plated) will ensure high quality and resistance to natural wear and tear over time. What is a Spring Stop? A spring style door stop is essentially the same as a rigid type but utilizes a spring construction rather than a solid piece. This style is somewhat more inexpensive than other types but carries many disadvantages.
The results were as follows; all hard surfaces (cement hardwood linoleum tile indoor outdoor carpet and commercial carpet) the results were similar enough not to explain the minute differences; the door was jammed almost immediately only allowing the door to open a crack while the alarm roared to life.

In summary both tests were conducted with various opening speeds and strengths.

He already had success in two rooms - the occupants never even knew that he was in their room. So when he got to Jennys room he felt very confident. No lights were on and it should be easy pickings. But when he tried to open the door it hit the lip of the Door Stop Alarm and set off the 120 dB alarm -- which is very loud. Needless to say Jennys room was not burglarized that night and she stayed safe.
