Window hardware


Roto expanded its Patio Alversa window hardware with the addition of new technical features designed to increase user comfort. The hardware’s range for parallel sliding and tilt and slide windows was enhanced to meet the requirements of builders. Enhancements include a new ball-mounted roller unit in all versions, which ensures quiet, smooth operation and reduced wear. The hardware is also designed with protection against jemmying in its factory configuration. For builders, this innovative roller unit technology means safe window guidance.
