Rare Earth Magnet
Previously only roller catches, ball catches or low-quality magnetic catches were available for keeping dummy doors closed (single and double dummy doors are usually for openings to vestibule and bedroom closets).
Ball and roller catches are noisy. The noisy “clickety-clack” of the opening and closing of doors with traditional mechanical catches is unappealing.
Strong and quiet earth magnets are now available by Precision Brand for dummy doors. Available for about the same price as a good quality ball or roller catch, they have an added advantage over conventional mechanical catches: they are hidden when the door is fully closed so that they are perfect where a clean modernist aesthetic is desired.
When installed, the positive and negative magnetic polarities should be installed slightly off-set from one-another to maximize the efficiency of the magnets’ closing function.
