PRO Magnetic Frag Racks - IceCap

The IceCap PRO Magnetic Frag Racks offer a practical, unobtrusive way to stage and hold coral frags inside a reef tank. The matte black profile sits close to the glass, blending into the tank background rather than drawing the eye, and the magnetic mount is strong enough to hold through walls up to 1/2 inch thick — covering most standard aquarium glass and acrylic builds.

The defining feature of these racks is the membrane-lined plug holes. Rather than relying on a fixed-diameter hole that works with only one plug standard, the flexible membrane grips the stem regardless of minor size variation, keeping frags upright and stable even in tanks with moderate flow. Stems up to 3/8 inch in diameter are accommodated securely.

The modular, magnetic design means the rack can be pulled off the glass and repositioned without draining the tank or disturbing livestock — useful when acclimating new frags to a specific light level or when accessing a corner of the tank for maintenance. Three size options let you match rack capacity to your workflow: the Small holds up to 8 frags, the Medium up to 23, and the Large up to 32.

Fit considerations are straightforward: verify your glass or acrylic wall does not exceed 1/2 inch thickness before ordering. The racks ship with a 1-year limited warranty covering defects in materials and workmanship from the date of purchase.
