Edward Hughes –
Easy to install and stays secure even in rough conditions. The internal collar holds the bag perfectly. No issues with tightening or loosening. Cleaned with soapy water and still works well after a few months of use.
Dylan Butler –
Fits well with my existing setup. The locking system prevents over-tightening, which was a problem with older models. The black color matches my boat’s deck. Slightly harder to install without the fasteners, but that’s expected.

Great quality and durable. The UV stabilized ABS resists sun damage. The collar keeps the container in place without shifting. Works perfectly with silicone sealant and stays tight over time.
