SimNet Hydro-link Pro Kit (A-HPK)
The SimNet Hydro-link Pro Kit (A-HPK / HPK-A) brings true hydraulic resistance and modulation to your simracing brake system by using a compact master cylinder + slave cylinder hydro body, combined with a tunable two-stage stack. Designed to integrate with SimNet SP Pro Load Cell pedals and the SimNet SHB-100 Load Cell handbrake, it lets you shape pedal feel from soft initial bite to firm lock-up for a more realistic cockpit.
Main Features
- Real hydraulic brake feel: feel the direct resistance of hydraulic fluid as you apply pressure.
- Hydro body with Master Cylinder + Slave Cylinder design for realistic modulation.
- Two-stage brake design: mix and match springs and elastomers to build your ideal resistance curve.
- Multiple stack configurations: one spring, two springs, spring + elastomer, or two elastomers.
- Wide tuning range using different spring rates and elastomer hardness levels.
- Preload adjustment via the slave cylinder cap for consistent pedal feel.
- Includes dedicated mounting plates for pedals and handbrake for a clean cockpit install.
- Built for advanced simracing control and repeatable inputs in competitive driving.

Compatibility & Accessories
Compatible with: SimNet SP Pro Load Cell pedals and SimNet SHB-100 Load Cell handbrake.
Installation tips for best results: use a rigid simracing cockpit (especially aluminum profile rigs) to maintain consistent pedal geometry and improve feedback precision. This kit is a perfect match for high-end setups built around a direct drive wheelbase, a racing dashboard, a shifter/handbrake combo, and a quick release (QR) steering wheel ecosystem.
Important notices (use & maintenance):
- Do not operate the A-HPK repeatedly without a proper stack/load installed. The kit is supplied without a stack/load pre-installed.
- If the slave cylinder piston gradually extends outward during empty operation, press the piston back by hand into its original position.
- Upright installation only. Do not install or use in an inverted (upside-down) position.
- On first use or after changing stacks, set the slave cylinder cap to maximum preload (5 mm position) to ensure the piston is fully seated.
- Keep the slave cylinder clean and free from dust/debris for smooth operation and long service life.
- Elastomers are consumable parts (wear items) and are not covered under warranty.
Benefits
Real hydraulic resistance for authentic braking feel. Highly tunable two-stage response with springs and elastomers. Cleaner modulation for trail braking and consistent lap-to-lap performance. Professional cockpit integration for advanced simracing pedals and handbrake control.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles.
Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need.
The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup.
Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room.
The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams.
The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money.
What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.
