The M-Rack Magnet PUK has been beautifully designed to complement your aquarium look by being as low profile as possible, yet remain highly functional.

Manufactured by experts in sealing electronics, the whole M-Rack concept was developed for a need to make better magnet accessories for aquariums, that won’t leak, will last a very long time and can be re-used rather than thrown away when you need something bigger, smaller or just different.

Enter M-Rack!

To get started with M-Rack you just need one or two magnet PUKs. From here you can attach whatever accessory plate you need and grow your mounting needs or size down and re-purpose the magnet for something else. By re-using the magnets for different things, this will help reduce the amount of plastic aquarium products and rare earth minerals and metal going to landfill.

Both halves of the magnet can be used wet or dry too – allowing you to put accessories on your weir box, in sumps or wherever you need.

To change a rack, all you need to do is push out the included rubber lock, pull the plate out, replace and push the lock back in. We recommend you do this periodically and clean the magnet and the lock to ensure future ease of use vs Coralline algae and detritus.
