The IVES SP90A3 is a side window lock designed to secure aluminum sidelight windows and narrow-frame window panels in residential and light commercial door assemblies. It ships in a bright brass finish, offering a clean, traditional look that coordinates with standard architectural hardware. Measuring 4.4 inches in length, 2.3 inches in width, and 0.8 inches in height, the SP90A3 has a compact profile suited to tight window frames and slim sidelite applications. Sold individually, it is a straightforward swap for worn or missing window locks on existing door systems and is a standard item for new-construction door hardware packages.
The SP90A3 is intended for use on aluminum sidelight windows and similar narrow window frames mounted adjacent to entry doors. It is well suited to residential new construction, light commercial tenant improvements, and renovation work where the existing window lock has failed or an upgrade in finish is needed. Door hardware installers and general contractors typically specify this lock when coordinating hardware finish across a full door and frame assembly. Its compact footprint makes it appropriate for slim sidelite frames where full-size locks will not fit.
Designed as an OEM-style replacement or new-installation lock for aluminum sidelight windows and narrow window frames in residential and light commercial door assemblies.
Installation is typically performed by door hardware technicians or general contractors as part of door and frame rough-in or finish work. Secure the window lock using the manufacturer-supplied or appropriately sized fasteners for the frame material. Ensure the window panel is properly aligned in the frame before marking and drilling mounting holes to avoid misalignment of the latch. Verify that the finished installation allows smooth operation without binding before closing out the work.
