Question: How much propane time do you have left in the tree once shutting off the main tank valve? I wouldnt want to leave the post under pressure.
Document: The threaded design is so poor that the clamping post stripped-out the first time that I tried to mount it. And I did not use much pressure - not even hand-tight. I am the second reviewer to mention this problem. Avoid this unit. Perhaps I will get lucky and will get an exchange that will work.
I got interested in a distrbution post after my local outdoors store stoping taking back the little 16oz cans of camp propane. I purchased this after looking on line and it store at a number of different designs. All the other brands attached directly to the tanks valve, and despite legs for stability would have put some pressure on the valve. For safety and stability I prefered this Century model, where the post clamps securely to the tank collar and then connects via hose.
Purchased this to use on an annual week long camping trip. Distribution post was as described and worked great. I really liked the way it mounted to the LP tank. With a hose going from the connection to the post it allows you to mount the post to the top of the tank without putting any pressure on the tank valve itself. Used a lantern, 2 burner camp stove, and an instant water heater simultaneously with no problems. There were no leaks and unit felt solid when assembled.
When I attempt to hook my stove to this Safety Post, the pressure drops to nothing within seconds. This is not a manufacturing error in the product. This post is simply not capable of handling really large demands. I should have known that, but I am somewhat of a rookie. I do plan on using this Safety Post every time I go camping due to its ability to connect my lantern and other smaller camp accessories.
works great every time i go camping, i had it for while. its much sturdy then other brands. few of my friends have purchased this item.prior to purchasing, i have done research on the propane tree. century two piece propane tree is A+++++.
This product is much much better than some of the rival models. Why? The outlets are further apart, andthe hose and fittings are of higher quality material. My mate (a long time engineer and builder) took one look at the other two brands I had ordered and said &#34;sent them back.&#34;  This post made the grade.
This product along with some extension hoses makes the use of all of my propane appliances so much better. I can connect my camp stove, lantern, and gas grill to one tank. I really like how securely it attaches to the tank unlike others that just connect to the valve and don't really have any other support this one is securely attached to the metal and so there are no support worries. Great product, love the carry pouch keeps everything together.
Bought this and 2 of the Coleman 8' extension hoses and everything worked well together! The post fit securely to the protector ring on a 20 lbs. propane tank. There were no leaks and the combination ran a Coleman 2 burner camp stove, a small propane fired grill, I also ran the lantern on the top of the post and all items worked simultaneously!! If you want to expand your camp kitchen, I would highly recommend this as an option.
I originally bought this model distribution post because it looked like it attached to a 20# propane tank securely. It did, it sits on the side of the tank and when I attached an 8' extension hose the combined weight of the hose and pole pulled my half full tank over. Could have been disasterous if I had something with a flame attached to the hose at the time.I contacted Amazon using their online return procedure, and they immediately emailed me a return authorization form and a printable shipping label.
This is a great propane tree. The reason I chose this one over the Coleman was due to the clamping mechanism. Most other trees hang off the propane valve. they may have a bracket or some other way of fastening to the tank, but ultimately there is stress on the valve. This one clamps to the metal ring on the top of the tank, and a hose goes around to the tank valve. There is zero stress on the tank valve.
