Worked great for the price
These worked great when replacing a beam under my house and provided reassuring support. You'll need a big wrench to turn the nut. They don't offer much lifting help but provide great support!!
Hello Ted! Thank you for sharing your experience — and for getting those hands-on with such an important project under your house. That kind of work takes patience, care, and the right tools. We're genuinely glad to hear that the jacks provided reassuring support while you were replacing the beam. Knowing they gave you that sense of stability and confidence during the job means a great deal to us. You're absolutely right about the nut — it does require a larger wrench to turn. That's by design to ensure secure, precise adjustments without slipping or stripping. We appreciate you pointing that out, as it's a helpful detail for others planning to use them. And your observation about the lifting capacity is fair and accurate. These jacks are designed primarily for support and load‑holding once the weight is in place, rather than heavy lifting. They're intended to hold things steady and level over time, and it sounds like they did exactly that for you. Thank you for trusting Beslands with such an important part of your home. If you ever need assistance in the future — or just want to share another project story — we're always here. Warmly, The Beslands Team

Versatile tool to have
Perfect adjustable jacks for a DYI guy. Used one to adjust height of my pontoon's helm seat. Used 3 to raise 500 lbs Kastle terracing concrete block. Next will be supporting floor joists in a 21" crawl space (their primary purpose).
Hello Me! Thank you for sharing such an impressive DIY journey with us! From adjusting the height of your pontoon's helm seat, to lifting a 500‑lb terracing concrete block, and soon supporting floor joists in a 21‑inch crawl space — your creative use of these adjustable jacks truly inspires us. Whether on water, on the ground, or in tight crawl spaces, knowing the jack is locked in place without a wobble lets you focus completely on the task at hand. Thank you for trusting Beslands as your partner in so many projects. May this stability and precision continue to support your next great idea — and make every DIY moment feel solid, safe, and stress‑free. Warmly, The Beslands Team

May this steadiness and assurance continue to support your home. Sincerely, The Beslands Team
