The H 3553 is an older style of casement lock-plated brass on zinc die-cast and used on older style wood casement windows. The three different keepers allow for most mounting applications whether it be a swing in or swing out casement window. Installation screws are included. Besides being used on casement windows, it is often used on cupboards and cabinets for that retro look.

The H 3514 casement window operator is a left hand aluminum square body type. It has a 9 in steel arm with a round disc on the tip (some older styles had a small wheel instead of a disc). The disc slides in the H 3529 casement track located on the bottom of the casement window. It is worm gear driven by a 3/8 in crank spindle. The matching crank handle that fits onto the crank spindle and installation screws are included. Mounting holes available are 3-7/8 and 4-3/4 in apart.
