Lock Fly Reel System Lime Spool Only
Our Lock spare spools are not just future-proof, they are brand proof also. Lock spools are being built as a shared standard across every Sunray reel going forward, and across our sister company, Finner too. That means you’ll be able to buy Sunray and Finner fly reels with total confidence: the same Lock spools will fit both brands, forever, for any reel.
No dead spools. No forced upgrades. Just one spool system that stays useful forever.


Don't panic, you can use your own fly lines too.
The fastest and easiest to load spare spool in the World
Our Lock spare spools and Lock hub are the result of 4 years of innovation—self-locating, self-aligning, and sight-free loading. You can literally load them with your eyes closed.
96% in the bin.
Don't believe the hype
Did you know that 96% of fly line packaging ends up in the bin? Why go through the hassle of buying backing and fly lines, paying for shipping, throwing away the packaging, and then tossing the product packaging too?
Many brands make bold claims about their eco-friendly credentials, but these often amount to greenwashing without real impact. Recycling, while valuable, is far less effective than assumed. Plastics are difficult to recycle due to contamination and the variety of polymers, with most ending up in landfills or incinerators.
Cardboard faces challenges too—wet or soiled materials are often non-recyclable. These limitations highlight the need for genuine solutions, like reducing waste at the source and creating products that eliminate unnecessary packaging, rather than relying on recycling systems that often fail to deliver on sustainability promises.
