HoopMaster Mighty Hoop 4.375” Magnetic Embroidery Frame

The Mighty Hoop 4.375” magnetic frame is a compact and efficient solution for small-area embroidery. Ideal for sleeves, babywear, hat backs, and other tight or hard-to-hoop locations, this frame provides excellent hold with reduced fabric distortion, making it a valuable tool for precision embroidery work.

Specification

• Internal Frame Area: 4.375" round / 111mm round
• Max. Embroidery Area: 3.5" round / 89mm round

We recommend leaving a minimum of 11mm at each side of the frame (internal frame area) to allow space for the needle and presser foot.

*Please note—this frame is not as strong as the square frames due to its round shape allowing a smaller number of magnets.

Key Features

• Compact Size for Small Designs: Ideal for left chest logos, sleeves, children’s garments, hat backs, and other narrow spaces.
• Strong Magnetic Grip: Firmly holds materials in place, even those that are thick or slippery, without the need for tightening.
• Minimises Hoop Marks: Magnetic pressure is evenly distributed, reducing the risk of hoop burns and fabric creasing.
• Improved Hooping Efficiency: Simplifies alignment and speeds up the hooping process, especially when used with the HoopMaster fixture system.

Compatibility

• ✅ Compatible with most industrial & commercial embroidery machines, including Brother PR Series & ZSK Sprint & Racer models. Check our compatibility guide for more information on other machine brands.
• ✅ Fits Brother PR series machines, including PR680W and PR1060W models.
• ⚠️ Important Notice for Brother PR Series Users:
  This frame does not automatically communicate its size to Brother PR machines. You must always perform a trace before starting embroidery to ensure that the needle and presser foot do not contact the frame. Failure to trace can result in machine damage and is not covered under warranty.
