Casement Restrictors

High quality restrictors and limit devices for casement windows

Casement window restrictorsDesigned to fit a wide range of window systems and materials, Caldwell can supply casement window restrictors and limit devices which have been manufactured to meet various requirements and stipulations – be it safety, performance, reliability or even set aesthetic parameters. Depending on specified requirements, we can supply both integrated and face mounted restrictors:

  • Face mounted restrictors: In cases where in-channel bar type restrictors cannot be fitted, (or it is advisable for them not to be fitted), Caldwell’s range of face mounted restrictors can offer superior ease of fitting.
  • Integrated restrictors: An alternative to installing a friction hinge and retrofitting a restrictor post-installation, Caldwell can also manufacture and supply friction hinges (friction stays) with an integrated restrictor for convenience and discrete aesthetics.
  • Limit devices: To limit the opening angle of a casement vent, Caldwell can provide limit devices – bar restrictors which are available in either releasable or non-releasable versions for a wide variety of window configurations. Limit devices are particularly suitable for use for when safety or cleaning is important, or when the end user wishes to precisely control levels of ventilation.
