CANTY sight glasses feature the FuseView™ window. Our unique fused glass windows far exceed all conventional tempered glass windows in safety and performance. By fusing glass to metal, a high pressure, high safety, hermetic seal is formed. What’s more, our windows can easily be removed for cleaning. CANTY windows do not have to be discarded, as do traditional tempered glass windows. The FuseViewCF™ features an integral heater designed to prevent and eliminate condensation. With the FuseViewCF™ you can be assured that your view will not be impeded by fog or vapor.
