Calculated Max Vertical Hold-guidance only: 0.1lb / 1.6oz / 45g
Due to how brittle Ferrite magnets are we always include a few extra to make up for any damage or chips either caused in packing or shipping
All Ferrite magnets are designed to be used in dry conditions. They are both hard and brittle by nature.
Care must be taken when handling these magnets as there is a danger of trapped fingers, pinched skin and flying shards of metal if carelessly handled.
Never allow Ferrite magnets to jump together or to jump to steel as they will likely shatter.
Suitable for usage up to a maximum of 80 degree Centigrade.
Always keep magnets away from items that may be damaged by the powerful magnetic field such as credit cards, computers, mobile phones, Cd's.
Not to be handled near to or by people with Pace makers or other medical devices.
The actual pull strengths will vary depending on other variables such as: Steel thickness (the thinner the steel the lower the pull strength), Steel Quality (for example pitted/corroded), Surface finish (painted, powder coated will result in a reduced pull force).
A safety and information sheet is sent out with all magnets.
WARNING - This magnet is VERY powerful and totally unsuitable for Children!!
