## Long description

Trixie ELEMENT expansion ring for 38 mm connections is an accessory developed to extend and adapt modular pet habitat components. Designed for systems that use 38 mm diameter joins, this expansion ring enables secure connection between panels or tubes and supports layout changes when building or modifying cages, pens or play areas for small animals. The product is compatible with Trixie ELEMENT modular parts and is intended to increase assembly flexibility without altering primary structural elements.
Advantages
The expansion ring provides a straightforward mechanical solution for joining or extending 38 mm ELEMENT components, offering reliable fit and repeatable positioning. Its design reduces the need for custom modification of panels or tubes and helps maintain stable connections under normal use. The ring is compact and lightweight, which minimizes added bulk to the enclosure while allowing reconfiguration of modules as needs change.
Suitable for
Extending runs of 38 mm modular tubes and panels
Adapting existing ELEMENT layouts to add extra sections or accessories
Repairing or replacing worn connection points in small animal enclosures
Temporary or permanent reconfiguration of cages, playpens, and exploration areas
Key specifications
Compatible connection diameter: 38 mm
Purpose: expansion/adapter for modular pet habitat components
Intended animals: small pets (such as rodents, rabbits, and similar-sized species)
Function: joins panels or tubes and increases layout flexibility
Form factor: compact ring designed for minimal added bulk
How to use
To install the expansion ring, align it with the 38 mm ends of the panels or tubes to be connected and press the components together until the ring seats securely. Ensure that the connected elements are properly seated and that there is no unwanted movement at the joint. If the existing configuration includes locking clips or screws, follow the original assembly steps to lock the connection after the ring is in place. For disassembly, reverse the steps and separate components gently to avoid deformation.
Usage recommendations
Verify compatibility with your specific Trixie ELEMENT parts before installation and inspect connection points periodically for wear. Use the expansion ring in standard indoor conditions and avoid exposing it to excessive force or outdoor weathering to preserve fit and function.
