Abstract
A pivot corner adapted for operative engagement with a sash balance brake assembly of a pivotable sash window is disclosed. The pivot corner comprises a housing having an axial bore and a pivot pin. The pivot pin has a first portion disposed within the bore and a second portion extending outwardly therefrom and adapted for operative engagement with the brake assembly. The axial bore and the first pin portion are complementarily octagonal in cross-section. The first pin portion has a cross-section sufficiently smaller than the cross-section of the axial bore to permit non-destructive rotation of the pin relative to the housing upon application of a predetermined torque.
