The Simpson J813 Floor Beam Leveler Jack Pier is an engineered leveling solution designed to deliver precise floor beam support and adjustment both during and after construction. Built by Simpson and made in the United States, this jack pier gives contractors and builders a reliable, adjustable pier for residential and light commercial applications where maintaining a level floor beam is critical to structural integrity.

Key Features

• Adjustable range of 8 to 13 inches - accommodates a variety of installation heights, reducing the need for custom shimming or multiple pier sizes on the job site
• 12-gauge steel plates - provide structural rigidity and long-term durability under load, so the pier maintains its performance well after installation
• 3/4" threaded rod - enables smooth, precise height adjustment so leveling can be dialed in accurately without guesswork
• 1 1/16" O.D. steel pipe - delivers robust vertical support that holds the assembly firmly in position once the correct height is set
• Engineered for leveling simplicity during and after construction - allows adjustments to be made post-build, giving builders and homeowners a practical path to correcting settling or uneven floors without major demolition
• Made in the United States - reflects consistent manufacturing quality and material standards that professionals can depend on

Why This Product

• Versatile adjustment range built into a single pier - the 8 to 13 inch span means one product handles multiple floor beam heights, streamlining procurement and reducing on-site inventory for floor leveling projects
• Post-construction adjustability - unlike fixed-height supports, this pier is specifically engineered to allow leveling corrections after the structure is complete, making it a practical long-term solution for settling floors
• All-steel construction for lasting load support - combining 12-gauge plates, a threaded rod, and steel pipe, the assembly is built to maintain structural performance under the sustained loads typical of floor beam applications
• Trusted Simpson engineering - backed by a brand that structural professionals rely on for code-relevant hardware, giving installers confidence in both performance and inspection compliance
