Octo Fracks™ (Frag Racks)


Available in both clear or black acrylic, with magnets or with “legs.”  Slots instead of holes is standard (except the pico/nano size) as you can fit more frags using slots (generally).  Custom sizes also available.

Legs can be any height up to 5″, either level or at an angle.  To avoid breakage during shipping, the legs will be sent unattached (U-Build). You can affix them with Scigrip 16 or Craftics 33.  I prefer Craftics 33 for this purpose as it comes in small 1.5oz tubes for around $5.  Scroll down for assembly instructions.

The powerful neodymium magnets will hold on glass 1/2″+!  Number of frags per rack will vary depending on total weight.

Slots are 1/2″ with 1/2″ in between each slot.  Holes (Nano) are 1/2″ diameter and approx. 1 1/4″ apart.

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.

Shipping will be combined on multiple products if possible, and you will receive a partial refund.  Most of my products are made to order and BY HAND!  Please allow a week for fabrication time (longer for Octo Lids™)  Shipping prices listed are to the contiguous U.S.  Please contact us if you live elsewhere and want a shipping quote.

How to assemble your Octo Frack™

Materials you’ll need: acrylic solvent, square, paper towel.


1.) (If necessary) Remove any protective paper from the acrylic pieces your are assembling.  Dry fit the legs in the dado slots to ensure they fit.  If one does not fit, swap it with another leg.  Acrylic sheets can vary slightly in thickness but I try to ensure they fit before shipping.

2.) Use acrylic cement such as Craftics 33 or Scigrip 16 and lay a generous bead into the dado.  Be careful as these cements can come out of the tube pretty fast!

3.) Fit the leg into the dado and push down firmly.  Depending on temperature and humidity, you may not have long before the cement starts to set up.

4.) Use a square to ensure your leg is at a 90° angle, press down gently and let the cement set up for 30 minutes.

5.) Repeat steps 1-4 on all remaining legs.

6.) Flip your frack over and place some light weights on top.  I like to use a few cans of vegetables.  Wait 30 minutes.

7.) Run a bead of cement in the seams to add strength.  Wait 30 minutes.

8.) Enjoy!

Remember, these types of syrupy acrylic cements are not as strong as the liquid types.  Care must be taken when handling your Oct Frack™.  If you have any questions, please feel free to contact me.
