• Loading capacity of bracket fastened to concrete with KB-TZ 1/2" x 3-3/4" (with an embedment depth of 3"using ASD allowable load values) or KH-EZ 1/2" x 4".
• The deection of L/150 was observed at the point of load application.
• The loads apply only when strut opening pointing upwards or downwards.
• The bracket’s own weight has been accounted for.
• Concrete strength minimum 3000 psi.
• Fastener loads based on no edge distance or anchor spacing effects. Reference Vol. 2 Hilti Anchoring Technical Guide for details.
• Engineer of record is responsible for verifying suitability of the components, connection, anchor selection and base material for any specic application.
• The application guidelines applicable to the anchor must be observed.Reference Vol. 2 Hilti Anchoring Technical Guide.
• Load values for steel are based on the lesser of allowable stress, 25,000 psi, or a deection limit of L/150 at the outer most loading point.
