This is a straight sided cast whole roller buckle with an antiqued brass effect finish, designed for use on a strap of 25mm (1") wide and ideal for use on bag straps etc.
A 'whole' buckle means that it has a bar across that holds the end of the strap down, rather than needing a separate loop of leather or metal after the buckle.
This buckle is made from a mix of metals rather than solid brass, so we do not recommend using this style for dog collars or horse tack.
