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

    Great Quality and Perfect for Creative Projector Effects
    Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
    Although designed as a shower curtain liner, I ended up using this for a completely different purpose and it worked perfectly. I placed it behind my study window as a projection screen for Halloween videos, and the results were fantastic. The material allowed the projector image to display clearly while still diffusing the light nicely for a great effect from outside. The quality was much better than expected, the material felt durable, and it was easy to position and work with. This product turned out to be incredibly versatile and offered excellent value for the money. If you enjoy creative decorating ideas or seasonal displays, this works brilliantly as an inexpensive projection screen alternative.

    Perfect length and actually stays in place.
    Size: 72"W x 75"L (Pack of 1), Color: 1a. Clear
    This liner solved a problem I didn’t realize was bothering me until I switched to it. The extra length makes a big difference—no more water sneaking out onto the floor or the curtain riding up while you’re showering. It hangs nicely and gives a cleaner, more finished look compared to standard sizes. The material feels thicker than the cheap liners you usually find, but not overly stiff. It drapes well and doesn’t stick to you while showering, which is a big plus. The magnets at the bottom actually work and help keep it in place against the tub, especially if you have any airflow in the bathroom. Installation was simple and the reinforced holes seem durable enough to last. Overall, it just does what it’s supposed to do without any fuss. For the price, it’s a solid upgrade and something I’d definitely buy again.

    Well made
    Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
    The magnets hold well. The grommets are sturdy. The plastic is a bit thick and doesn't like to lie flat against the tub so it is constantly brushing you while you shower.

    Exactly what they say it is.
    Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
    Appears to work exactly as advertised, and quality is very satisfactory, which is always a pleasant surprise on Amazon. Magnets are strong enough, plastic feels pliable and durable. Don't forget the rings aren't included.
