Notes:
Allowable tension & shear load capacities are calculated using an applied safety factor of 3.0 1.
Allowable working load must be the lesser of product allowable tension & shear loads showing above table. 2.
NFPA® 13 design requirements are 5 times the weight of the water filled pipe plus 250 lbs. 3.
MSS requires the safety factor of 3.5 4.
Allowable loads for anchors to resist short term loads such as earthquake or wind may be increased by 33.33% for the duration 5.
of the load where permitted by code.
Step 1 - Construct the necessary wood form.
Step 2 - Assemble anchor to
wood form using a hammer.
Step 4 - After concrete is cured,
remove wood form.
Step 6 -Push-in threaded rod.
