All SlingRings are subject to:
Soaking in bleach and then a full washer/dryer cycle
Freezing followed by additional impact testing
Heating followed by additional pull testing
As part of the manufacturing stage the following tests are also preformed:
Pull test each individual ring to 250 pounds
1 ring per batch pulled to destruction
Periodic rings are sent for testing in an independent laboratory to verify crush and deformation testing
Rings are also sent to testing agencies in the USA and in other countries to verify heavy metal and toxin free
Our rings and manufacturing process are RoHS compliant and lead and nickel free.
All rings are measured from the inside edge to the other inside edge. This is their inner diameter (ID)
The aluminum rings are SMALL 2" (5 cm) MED 2.5" (6.4 cm), LARGE 3" (7.6 cm) and 0.25" (.64 cm) thick.
In general, use small rings for thin, slippery fabrics or water slings. Use medium rings for shirt-weight fabrics. Use large rings for pants weight or winter weight fabrics, for very "grippy" fabrics and for 2 layer or reversible slings. Ring size does not depend on the height or weight of you or your baby.
