Overview:

Ideally suited for bracket racers and weekend warriors alike, Q-Series carburetors are purpose-built for the dragstrip. To combat the g's experienced during hard launches, Q-Series carbs are equipped with notched floats and secondary jet extensions. The high-flow aluminum main body isn't just lightweight, but it also features recessed air bleed cavities for improved air flow. Die-cast venturi are machined to exacting tolerances for outstanding throttle response. Billet metering blocks ensure a uniform fuel curve, while throttle-bodies enhance durability. For those days when track conditions vary from one pass to the next, QFT's QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries. The Q-Series is our most comprehensive line of carburetors, with applications available for use with gasoline, methanol, and E85 fuels, forced induction, drag race, circle track, and comes in both vacuum and mechanical secondary models. Lightweight aluminum main body Vacuum and mechanical secondary models available Aluminum fuel bowls with dual sight glass windows Billet metering blocks with 4-corner idle system Changeable idle feed and power valve channel restrictions Billet aluminum throttle body provides exceptional precision and strength PTFE coated and sealed shafts

    Functional divider for windows privacy
    Size: 8 Panel, Color: White, Size: 8 Panel, Color: White
    I ordered both a six and eight panel version of the white divider. There was some confusion on the FedEx deliveries. The eight panel divider arrived at first, but Amazon showed both as delivered. I had to contact both the seller and Amazon to learn that the six panel divider was to arrive the following day by FedEx, which did occur. Both the boxes were a bit dirty and had some small punctures. This divider had a top area and bottom area set of plastic wrap tapes, both of which were loose or undone. (The eight panel divider was not so, and properly wrapped.) The top of thid divider looked a little dirty, but passable/cleanable. The seller should consider wrapping the entire product with bubble wrap to protect against potential delivery/shipping physical and water damage. (FedEx left the box by my outside door, which could have gotten potentially soaked in rain. One better be home to take delivery if the weather is bad.) This said, the divider was easy to set up, with all the metal hinges working. No assembly was required, just unboxing and standing up. The left side was a little uneven on the bottom with the first panel, but ok. In combination with my mini-blinds, it provides the additional layer of privacy I desired. I even don't notice outside headlights and tailights through the windows with my room lights on. Additionally, the divider is easy to adjust to allow access to my windows for opening and closing. So, no need for me to hang curtains and damage my drywall. Overall I give the product a C grade because of the lack of protection for the FedEx shipping. (As a former University told me years ago, "The A has been cheapened. In this class you will work for an A." And, I got a B. So, I am a bit jaded. :-)) Lastly, if one had cats and dogs, or even small children, the divider could be easy for them to topple over. I would not consider these dividerd in that case. My motto is, "Safety first."

    Great Dividers
    Size: 6 Panel-120"W, Color: Beige
    Love these!! Many uses. Simple, nice looking, sturdy overall. Well made. Bought to divide the unsightly storage area from the calm rest area in the basement. Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.
