The PSS Shaft Seal is the number one selling marine mechanical seal worldwide and is installed as standard equipment by many of the worlds most reputable boat builders / yards. The PSS Shaft Seal is also recognized as the premiere retrofit (aftermarket) seal on the world market. Certified by Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages and value of installing the PSS as it eliminates the maintenance, constant adjustment & cost associated with traditional packing type glands. Aside from these benefits, the PSS Shaft Seal helps to eliminate water in the bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal can be easily retrofitted and is available for shafts ranging from 3/4" (20mm) to 6" (150mm).
The PSS Shaft Seal is a mechanical face seal that is created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This compression (pre-load) maintains contact between the faces and allows the PSS to compensate for the thrust from the propeller. The carbon flange is bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two o-rings that are recessed into the bore of the collar. These o-rings rotate with the shaft and stainless steel rotor and do not experience wear during operation.
**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration. PYI suggests as preventative maintenance that the PSS bellow be replaced in six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."
Bellows may need to be more frequently inspected in an environment where non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.
The Maintenance Kit includes the items you need to properly maintain your PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings, five (5) set screws, four (4) new hose clamps and an allen key.

Works well, but it doesn't come with drywall anchors
Bought it to wall mount my wifi router.
The whole thing is very small, but the straps are very long, so it can support many devices. The straps also get reasonably tight.
Installation is easy, it's nice that it comes with a level.
Annoying that it only comes with six screws, and no drywall anchors. So you either have those, have to go get them, or screw it to a stud (which you probably should do depending on how he heavy the object you want to mount is).

Clean, sturdy way to mount a cable box/router (easy install)
Used this TotalMount to get my cable box/router off the shelf and tidy up the setup behind the TV. Install was straightforward (screws/anchors included), and the mount feels solid once it’s on the wall. The adjustable fit is the best part—it held my device snug without bending or wobbling, and there’s still enough airflow so it doesn’t feel “choked” in place.
It also helps a lot with cable management since everything stays in one spot instead of hanging or sliding around. Tip: measure your device first and lightly tighten, then do the final snug once it’s centered. Overall, great value if you want a cleaner, more organized setup.

Used it to hang two routers on the wall
This product was surprisingly good. For my purposes it was better than it needed to be. The drywall screws provided were very easy to use. I attached one side of the mount to a stud but I think for most purposes the drywall screws would have been adequate. I was surprised that they had channels in the plastic for the straps. This certainly made the molds for this product more expensive to make, but it made the straps easier to thread through the mount than if the had just made it so the straps went between the device and the wall. The product had a level. For my purposes it would have been fine without that but it did make it a little easier to install.
I mounted two routers (one was our network router and the other was a router that provided a land line telephone) side by side in this mount. I separated them a bit so as to allow each to cool. It was a nice improvement over having the routers flopping around on a desk and periodically falling on the floor. I gave it five stars overall. It was nicely built, I couldn't see what they could have done better, the price seemed reasonable and it got here in a timely way.

Easy install and perfect mount for PS3 Slim
I struggled to find a mount for my PS3 slim and as I already have TotalMount's PS4 Slim mount, I had the utmost trust in this one.
Installation is already easy and made easier with the built-in level. Simply hold level and screw/drill in screws. But honestly, one of the best things about this mount are the included screws. Their thick threading ensures that the mount being ripped off or loosened is almost impossible.
As for the quality of the mount holding my PS3 Slim, which isn't exactly light (7 lbs), no complaints. It was pain to set up within the straps as I needed a second set of hands, but it is very secure and I trust it's not going anywhere. But as a tip for anyone installing heavier objects, make sure the adjuster buckles are near the top. Because of the PS3's weight, it unavoidably weighed the straps down so I found that tightening the console near the top secures it in places without gravity playing too much of a role. But I recommend do trying to avoid using this mount for heavier things in general.

Excellent For the Price
The mount is much smaller than I had originally thought but that does not really pose a problem as the straps are excessively long allowing for large items. It is very straight forward and easy to install. The plastic buckle on the provided straps are less than impressive as they do not tighten as much as I would like. That having said that I'm not in fear of it falling because each is secure and snug against the console.
If your item is larger than the mount than it will be able to move length-wise as the straps are not connected to the mount but rather you push them through the provided slots. On my next install, I'm going to try using a wedge or clamp that will keep the straps secured to the mount to mitigate this.
The install hardware consist of 6 bear-claw style drywall screws. These are have very poor quality control as 2 of the screws had 1/4in metal shavings attached to them one of which sliced open my finger during install. I was using a simple screwdriver and was being moderately careful as to not damage the plastic. I recommend using anchors that you are more familiar with. Also I will be using washers next time as the holes in the plastic have a small lip in them that the screw is supposed to snug up to and I don't feel as comfortable with it after actually mounting the console. I did a fair amount of tugging on the straps to try and tighten them and was worried I may pull the mount loose.
Over all, I very much like this item. It is very versatile and you cannot beat the price. i will defiantly be buying this again and using my own hardware to mount so that I feel more secure putting expensive items 6 ft off the ground.
