Since they are going to be in place for several months making slow adjustments, I didn't want to use my regular ones. As others have mentioned in their reviews of similar products, these posts come in several pieces and must be placed on very level pads or they will slip off. The threads are not acme type and must be well lubricated with grease before any heavy loading or the threads will spall or freeze up. The turning bar supplied is also very anemic and is likely to bend if trying to make adjustments under heavy loads. Still, for a low cost, light duty adjustable post they aren't bad. Just be aware of their limitations and don't expect them to perform as well as units like the JET models. Review: Arrived rusty in the box. - I bought one of these and one of the Tiger Brand. The quality of this jack post does not compare with the Tiger brand. It arrived RUSTY in the box. If it rusts in the box, I'm sure it will really rust in my crawlspace. I won't be using this in my home. The Tiger brand one met all my expectations, and I would buy that one instead. This marshall post has thinner metal, and is extended with a small metal bar, rather than a wrench --- which makes it difficult to put some serious force into it. Also, I'm sure I'll loose the small metal bar eventually, whereas I will always own a wrench. ## Features - Supports Sagging Floors, Weak Beams And Warping Stairways - Grooved Pin And Plain Pin - Flow-Coated With Red, Corrosion-Resistant Paint - From The Brand Name: Marshall Stamping ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LF5UPY | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #1,060,696 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,291 in Industrial Floor Jacks | | Brand | Marshall Stamping | | Brand Name | Marshall Stamping | | Color | Red | | Customer Reviews | 4.1 4.1 out of 5 stars (6) | | Date First Available | January 16, 2007 | | Global Trade Identification Number | 00725697160003 | | Included Components | Building Materials & Ladders;Scaffolding, Pump & Wall Jacks;scaffolding-equipment | | Item Dimensions LxWxH | 9.81 x 5.02 x 2.92 inches | | Item Package Dimensions L x W x H | 11.8 x 5.1 x 3.2 inches | | Item dimensions L x W x H | 9.81 x 5.02 x 2.92 inches | | Load Capacity | 1.5E+4 Pounds | | Manufacturer | Marshall Stamping | | Model Name | JP16 | | Number of Items | 1 | | OEM Part Number | 725697160003 | | Package Weight | 4.25 Pounds | | Part Number | JP16 | | UPC | 725697160003 | | Warranty Description | Warranty | ## Product Details - **Brand:** Marshall Stamping - **Color:** Red - **Load Capacity:** 1.5E+4 Pounds - **Material:** Alloy Steel - **Vehicle Service Type:** ATV ## Images ![JP16 "Extend-o-post" Adjustable Floor Jackpost - 12" to 16" - Image 1](https://m.media-amazon.com/images/I/71p7JSsSY3L.jpg) ## Customer Reviews ### ⭐⭐⭐ Flimsy but inexpensive *by C***K on February 23, 2012* I purchased 3 of these to aid in a releveling project on an old house.
