Octo Strong Cup/Sock Holder

(2 customer reviews)


Finally, someone smart (me) is now offering the most versatile cup/sock holders ever made… with magnets!



My legendary Octo Pods™ are utilized to keep these filter cup/sock holders in place, and allow you to move them around, or from sump to sump. Made from 1/4″ acrylic and available for sizes 4″ and 7″, single and double configurations.  External magnet needs about .625″ for clearance.


4” Single – 6”w x 7”d x 2”h
4” Double – 11”w x 7”d x 2”h
7” Single – 9”w x 9”d x 2.5”h
7” Double – 16.5”w x 9”d x 2.5”h

I use N52 neodymium magnets. Rare earth magnets are not reef safe on their own, so I fabricate custom acrylic pods that encapsulate the magnets and keep them away from your water. Please visit the magnet warning page for more information on these magnets.


My products are made to order, custom! Please allow up to 10 business days for fabrication time for most products. Because my products are made to order, fulfillment time can rarely take longer. Full custom orders can take up to four weeks to complete. Please let me know ahead of time if this may be an issue. Shipping prices listed are to the contiguous U.S. Please contact me if you live elsewhere and want a shipping quote. Because my products are handmade and/or hand assembled, there may be small irregularities (fingerprints, marring, hair, etc) which will not effect the performance of your product.
