What range of height adjustment does this jack offer and will it fit my trailer?

The jack adjusts from 21.7" to 36.6" overall height to match low‑profile and small trailers; note the base is fixed rather than removable for extra stability. The bolt‑on kit fits trailer frames with rail widths between 3" and 5".

How easy is it to operate and install the Kohree jack?

Installation is straightforward with the included mounting hardware; the bolt‑on design avoids welding and lets you secure the jack directly to the trailer frame. Operation is simplified by a detachable rubberized handle that provides non‑slip grip and makes cranking faster and more comfortable.

• Detachable ergonomic handle reduces crank effort up to ~30%
• 90° swivel locks the jack in travel or deployed positions for convenience

Will this jack hold up in outdoor and marine environments?

Built from heavy‑gauge steel with a galvanized surface, the jack resists rust and wear when exposed to weather. Its durable construction and corrosion‑resistant finish make it suitable for boat trailers and coastal use when rinsed and maintained periodically.
