BISupply House Jacks for Leveling Crawlspace 3 Pack - Adjustable

In this review of the BISupply House Jacks for Leveling Crawlspace 3 Pack the bottom line is straightforward: this is a practical temporary solution for homeowners and contractors who need to lift and stabilize sagging floors or beams during repairs. The kit's biggest selling point is its adjustable screw jack that reaches from 54 to 150in, giving a very wide range of supporting height while offering substantial load capacity at lower settings. For anyone tackling floor leveling, crawlspace shoring, or temporary beam support, these posts deliver predictable mechanical support during renovation work.

Key Features

• Adjustable height: The screw jack adjusts from 54 to 150in, which covers most crawlspace and basement lift needs without requiring multiple parts.
• High load capacity: Each jack supports up to 11,200lb at its minimum height and still carries significant loads at full extension, providing stability during repair work.
• Durable construction: Made from ISO9001 certified oxide finished steel with a welded-on floor plate for a sturdy contact surface on concrete.
• Complete hardware: The set includes a turning bar, a large roof plate and four locking pins to secure the screw position during use.
• Three pack convenience: Supplied as a 3 pack so multiple support points can be established for joists, trusses, or bouncy floors without sourcing individual posts.

Who It's For

These adjustable column jacks are best for homeowners, handypersons, and small contractors who need a temporary, mechanical support while shoring up sagging floors, replacing beams, or stabilizing a crawlspace during repairs. The extended height range makes them particularly useful where floor-to-ceiling distances vary or where temporary shoring must reach high joists.

They are not intended as permanent supports, so structural engineers or buyers seeking a permanent foundation fix should look for certified permanent columns or consult a contractor. Also, if you require fine precision leveling under heavy continuous loads at full extension, consider professional-grade, permanent solutions in addition to these temporary jacks.
