I need a conduit penetration detail for a UL451 assembly

Looking for appropriate 1/2 diameter anchor (1/2-13) for exterior post-installed anchors for a switchboard that requires mounting hardware (as seismically tested) with a torque value of 60 ft. lbs. Fixture holes are 0.625 with a pipe spacer of 2.10 inches. Would a Hilti KB TZ2 anchor be appropriate for this?

What should be the Pre-drilled hole size (dh) for hot dip galvanized steel angle when using 1/2 diameter Kwik Bolt TZ2. Should it be slightly larger than 9/16 specified in ESR 4266 table 1 ?

The loads are extremely small ~500lb for shear and 175lb for tension so I was looking at using the 3/8, but the minimum the software will let me use is 1/2. What's the reason behind this? I looked in the ESR and couldn't figure out why I can't use 3/8.

Hi I haven't received links to quiz for the past two webinars that I attended

A floor sink is penetrating my fourth floor. It is a deep floor sink that sets 4 inches below the deck in and has concrete poured up to the side of it. The manufacturer does not provide UL design to guarantee my two hour rating with the cast-iron sink alone. Can Hilti provide an engineered judgment to use a blanket wrap and ma...

The product data for the X-U fasteners include allowable shear and tension values for sheet steel. The ICC-ES Report (ESR-2269) does not include this table. Is there documentation that includes this table, besides the product data, that DSA would find acceptable?

Is the webinar for today cancelled?
