The Legge 1851 Chain Bolt is designed as a simple and cost effective method to secure the inactive leaf of a double leaf doorset. The reversible bevelled bolt automatically latches and secures the door leaf when closed and is easily retracted utilising the attached chain.

The Legge 1861 Restrictor Chain is also designed as a simple method of restricting the door opening swing. The spring mechanism reduces the force and angle of the opening swing eliminating possible damage to the door, hardware and/or wall.
