Strength of materials used to make my Safety Harnesses
All my Safety Harnesses are for walking and helping to support your child in their chair, stroller or wheelchair but like any parent, I know the strength of a 4 year old throwing a tantrum.
Many of my customers tell me that their child has broken a toddler harness in the past. In some cases, the parents tell me their child has broken every toddler harness they have tried.
I know the frustration and the danger of being disappointed by the quality and durability of a toddler harness that I thought I could trust. It was that very frustration that lead me to design my own Safety Harness in the first place.
The stitching method that I use on my harnesses is boardering on excessive. I use reinforced zigzag stitching on all the seams to make sure I have complete and utter confidence in the strength and durability of every harness that I make. I'm not saying that my Safety Harnesses are unbreakable, but I am 100% confident that the stiching won't come apart!!
And where possible, I have obtained strength data for some of the materials I use in my Safety Harnesses.
Polypropolene Webbing
Some toddler harnesses on the market are made with nylon webbing which is very soft and very nice to the touch.
However, I find nylon webbing to be extremely slippery. The last thing I wanted was a Safety Harness that would slip and slide out of shape when my oldest decided to throw one of his fits.
The polypropolene webbing has enough texture to it to keep it's shape in all sorts of situations. Of course it's the sliders on the harness that prevent the slippage and the sliders, in combination with the texture of the polypropolene webbing, keep the Safety Harness securely on your child.
Naturally, all this depends on you fitting the Safety Harness snuggly on your child in the first place. A proper fit is critical. Loose pants won't fall if you're standing still, but take a few steps...!
Black, denim blue, red polypropylene webbing
- break strength: 607 pounds
Purple polypropylene webbing
- break strength: approximately 700 pounds
Pink polypropylene webbing
- strength break: 379 pounds
Welded metal O-rings
1 ½ inch metal O-rings used in the Child-to-Adult Safety Harnesses and Child Harnesses with detachable leads
- in excess of 500 pounds. The strength of the O-ring is determined by the weld and since I must use welded rings to protect the webbing, these are the lightest rings available to me.
Metal Snap Hooks
- light-weight metal snap hooks used with the Child Harness - no data available
- heavy-weight metal snap hooks used with the Child-to-Adult Harness - same snap hooks that are used on tack for horses
