The key to the design of the smooth-glide Dreamscreen screen door is a guide rail end cap molded from an acetal-based Lubriloy alloy from LNP Engineering Plastics. The screen doors are designed to glide back and forth on heavy duty aluminum rails. The purpose of the rails is to reduce friction and keep the doors in place as they’re opened and closed.

In other retractable screen doors, plastic end caps often come with an externally-applied lubricant, typically a silicone wax. The molder of the Dreamscreen end caps, Octex of Sarasota, FL, recommended an internally lubricated plastic to improve quality and reduce cost. Lubriloy was ultimately selected over an internally lubricated nylon because gave the needed properties and was less expensive than plastics using PTFE as an internal lubricant.
