Octo Strong Cup/Sock Holder

(4 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.

Plastics are fragile which can break and scratch easily. Always handle with care. Surface can be cleaned with a very diluted soapy water mixture and a soft microfiber cloth.

This product is warranted to be free of defects for the lifetime of the product. We will, at my discretion, repair or replace your product at no charge during this period (See the Warranty page for more info.)

    Order this with a very specific measurements that I want and it came the way I asked for. It took a while to have it shipped (holiday season) but still was happy when I got my order. The quality is very good and magnet really sticks well. This is a very solid product.
