Box Stop Hinge
These hinges are sold by the pair.
Brusso box hinges are built with a squared barrel and can only open to 100 degrees. For boxes this is sufficient to prevent the lid from falling back but on large boxes and chests an additional means of support will be required. As is typical of Brusso products this solid brass hinge is finely machined and finished and employs a stainless steel pin for long wear resistant life.
