Prime-line MP5026 Storm Door Chain and Spring

Product Description

The PRIME-LINE MP5026 is a storm door chain and spring assembly designed to control the closing motion of a storm door. This type of hardware provides tension and restraint that keeps a storm door from slamming shut or swinging open uncontrolled. The chain component limits door travel while the spring provides return tension, working together to extend door hardware service life and reduce frame stress. This assembly is a direct replacement part suited for residential storm door maintenance and repair, typically installed by a handyman or general contractor during routine door hardware service.

This chain and spring assembly is intended for use on standard residential storm doors. It mounts between the door frame and the door panel to manage door speed and travel range. The assembly is a common replacement component when the original hardware has stretched, broken, or lost tension, resulting in uncontrolled door movement. Installation is straightforward and does not require specialty tools, making it a practical service item for routine storm door upkeep.
