6 Selecting Magnet Anchor Size
The following is an example to illustrate the selection of proper anchors to install a Magnet in a
building with 2000 psi (13.8 MPa) concrete. For this example the area is not under seismic
requirements.
1.
Determine magnet clamping force (for the Magnet: 2500 lbs + 200 lbs = 2700 lbs or 11,100
N + 900 N = 12,000 N).
2.
Refer to the examples of anchor vendor catalogs below to select anchor diameter and
embedment which meets the clamping force (tension) determined in Step 1.
Diameter : Min. 0.625 inch Max. 1.25 inch
For 8 inch embedment select 3/4 inch diameter
For 4.5 inch embedment select 1 inch diameter
or
Diameter : Min. M16 Max. M32
For 130 mm embedment select M20 diameter
For 114 mm embedment select M24 diameter
3. The vendor instructions and torque to the maximum recommended level for the anchor
selected in Step 2 must be provided to the RF Shield Room vendor for proper installation of
the anchor and equipment.
