Rental FAQs

What is a post shore?

An adjustable steel post, also called a ceiling jack, that holds a ceiling, beam or slab up temporarily during construction or repairs. You set the height with the pin, then fine-tune it with the screw.

How much weight can a post shore hold?

It depends on the height. A Post Shore #0 holds 12,000 lb at 4 ft, while a Post Shore #4 holds 2,400 lb at 15 ft. The taller the shore is set, the less it holds. Every product page has a drawing with the load at each height.

What is the difference between Post Shore #1 and #2?

They overlap. #1 adjusts from 5 ft 9 in to 10 ft 3 in, and #2 from 6 ft 6 in to 11 ft. Both hold the same load at the same height, so pick the one whose range fits your ceiling best.

Which post shore do I need for a 12 ft ceiling?

A Post Shore #3 (8 ft 6 in to 13 ft) or #4 (10 ft 6 in to 16 ft). Both hold 4,000 lb at 12 ft.

Are the loads already reduced for safety?

Yes. The numbers are allowable working loads with a 2.5 to 1 safety factor. For structural work, have a qualified person plan the shoring.

Do you deliver?

Yes, to all five NYC boroughs.
