The box is located on the wall of the central lock keeper control building (see picture above). Inside the box, which can be opened with a CRT boaters key, are the Leicester Line leaflets, which are updated every two years by IWA Leicestershire Branch. The leaflets contain information and a map of the Leicester Line section of the Grand Union Canal and the navigable river Soar, through to Sawley Lock. The branch hopes to fit more boxes at locations along the Leicester Line. A pdf of the leaflet is available to download. Other boxes containing the leaflets are available at Watford Locks, Foxton Locks and Castle Gardens Leicester.
