Select the closest size Collar from the table below (Choose the smaller size if in doubt)

Bend the Collar to the desired height & width by hand.

  • It will stay in the shape you set it.
  • Bend the Collar to clear the clavicles (collar bones) if necessary.
  • A chin pad can be added to the chest portion of the Collar for extra padding if needed.
  • Use accessories for extra flexion and extension support.

Final Checks

  • Check that the Collar fits snugly under the chin.
  • The neckstrap should be around the back of the neck only.
  • For extra support use the Neck Pad or the Extension Pads (see accessories) to resist extension of the neck.
  • Use the Anterior Support to rigidify the Collar, if needed (see accessories).

Pediatric Headmaster Collars are softer and may be fitted to children needing head support as young as 6 months of age

The Headmaster Collar is now 100% Latex Free.


“I am an OT in Alberta who works at the ALS Clinic in Calgary. I have been in this position for 5 years and have always found head drop a huge challenge with this population. I use your Head Master collar on a regular basis but have recently discovered the anterior support piece accessory. I have only fit it with two clients over the past couple weeks since receiving the pieces (we only purchased two to see how they work) and am thrilled to say they have both been fit with great success! Thank you so much for your continued work. This is a great product.”
