COMP Cams Super Valve Lock Eb11/32-.050 - Set of 100Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.
Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross-section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock. This creates a collet effect that binds the two together. The more spring force exerted on the retainer (as the valve opens), the more force applied by the collet effect to keep the retainer and lock in place. With the emergence of valve sizes other than the standard 5/16", 11/32" and 3/8", it is important to make sure the valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small. Our line of stock replacement 7 valve locks for stock engine rebuilds are recommended only for street applications with lighter valve spring loads and are stamped and hardened for superior wear resistance. Also available are machined 7 locks and titanium Super 7 Locks for some applications. They offer the same valve spring location accuracy as our Super Locks without the need to change to 10 degree retainers.Shipping Notes

It's perfect for my needs and space. I'm using it as a design wall for my quilting projects.

Decent at dampening sound
Color: Grey, Color: Grey
This partition was easy to assemble and is stable. My husband and I both work from home, and the desire was to have a sound barrier. It definitely dampens the noise. If it was another foot taller, that would be even better at dampening the noise. Obviously, we still hear one another quite well, but the partition simply softens the noise of each other.

Easy Install, Great Quality, Mobile Partition
Color: Grey
This is the easiest install I've ever had in my life, took about 5 minutes. These panels come pre-assembled, minus the wheels, which screw into the base pieces in pairs. The material is a very pleasant "corporate grey" - I only worry about its color fastness over time.
I needed a practical solution for my garage, which has glass garage doors that let in a ton of sun/heat and even with privacy film still parade around my tools and belongings visibly to anyone walking by. These partitions are functional for both of my needs, and if I have a visitor needing to park in my second spot it takes 5 seconds to wheel these out of the way.

Nice, convenient partition that absorbs sound
Color: Grey, Color: Grey
What stood out
* Instant partition: This 3-panel foldable office partition helps to create quiet zones in a shared room, and it genuinely helped carve out a more focused space without a major renovation. The panels feel substantial yet easy to move thanks to the wheels, so I can roll them into position when I need privacy or a professional background for video meetings. I can fold them flat against a wall when I don’t nee them. The aluminum frame gives it enough rigidity to stay upright, and the gray finish is neutral. The height and width are generous for desktop setups, meetings, or study areas, and because it’s modular you can arrange it in L-shapes, straight lines, or even semi-circles. The mobility makes it flexible for dynamic spaces — roll it out for working hours, tuck it away after.
* Sound insulation: It's heavy, which is better for sound isolation. The sound-dampening design isn’t miracle acoustic treatment, but it noticeably softens background chatter and echoes — enough to make video calls and focused work feel less disrupted.
* Assembly is super easy, but I would recommend to have two people to make it easier.
What to keep in mind
* It’s not sound-proof like a built-in wall, so loud noises still carry; it’s best for softening ambient sounds, not blocking them completely.
* The gray color is neutral, but if your room palette is bold you might want to accent with décor so it doesn’t look utilitarian. You can also tack posters and light pictures to the the gray frames.
* It's pricey, but worth it in my opinion.
