The swivel retainer is designed to hold the swivel on the outside of the cage where it can be easily accessed while protected from the reach of the animal. Two designs are available. The first is a front mounting clip, and the second mounts to the top of the cage via a post and foot and is suitable for all models of solid bottom cages


Lomir retainers are manufactured from stainless steel and high-impact plastic. They are available in multiple designs, selected according to the type of cage in use.

  • Channels: choose between single and double channels
  • Materials: high-impact thermoplastic, with stainless steel hypodermic tubing
  • Leak protection: teflon seals
  • Reuse: with proper care and sterilization, swivels are resusable
  • Plastic meets FDA requirements
  • Part of a set: Lomir swivels can be used as a part of a rodent infusion system that includes a jacket, tether, swivel, swivel-tether connector and swivel retainer. We can provide all of these components.
  • Pre-sterilization available
  • Custom sizes can be manufactured, upon request.

Rodent and small animal infusion sets may be purchased complete or as individual components. All rodent infusion products are shipped with complete instructions for set-up, use and care. Sterilization is also available.
