The No.85 is a solid brass window spring bolt designed for
installation in the wood stile of a vertically sliding sash.
This type of hardware is commonly used in pairs on light
weight, single hung sash in lieu of a balance system or sash
lock, and is designed to be press-fit into a 3/8" diameter
hole bored through the sash stile.
A hole to accept the spring plunger is then bored in the
window jamb to hold the sash at any desired height.
The No. 85 is precision turned solid brass with a
stainless steel spring.
Similar to the Stanley spring bolts shown at the bottom of
the page but superior in materials and workmanship.
These bolts were also used to hold interior screens in
place for outswinging casement window applications.
Housing dimensions: 1 7/8" x 3/8"
Overall length: 3 3/8"
Shown above in 4 finishes Unlacquered Brass, Oil Rubbed Bronze, Satin Nickel, and Polished Nickel.
