1.Visually inspect the support hole for the correct diameter, length and direction to ensure the anchor shell fit into the hole ensure anchor shell anchor or pre-load sufficiently.
2.If the diameter is too small the Mechanical Anchor shell will not fit into the hole.
3.If too large the Mechanical Anchor shell will not anchor or pre-load sufficiently.
4.If drilled hole, too short or in the wrong direction then the Mechanical Anchor will not achieve the intended support length required
5.It is of critical importance the hole is drilled as close to 90 ° degrees to the hanging as possible, not less than 70 ° degrees
