Simpson Strong-Tie THD37400CS Installation Overview

  1. Drill a hole in the base material using a carbide drill bit of the same diameter as the anchor.

  3. Tighten the anchor into the base material until the bottom of the countersunk head contacts the fixture.

NOTE: Holes in metal fixtures to be mounted should match the diameter specified in the table above. Use a Titen HD screw anchor one time only—installing the anchor multiple times may result in excessive thread wear and reduce load capacity. Do not use impact wrenches to install into hollow CMU. Oversized holes in base material will reduce or eliminate the mechanical interlock of the threads with the base material and reduce the anchor's load capacity. Installation of concrete screw generally is influenced by many factors such as but not limited to, concrete compressive strength, type of aggregate, installation location, installation direction and tools used for installation.

Would buy again
Color: White, Size: Standard (Pack of 2)
This is a good pillow if you like them firm and thin. I let them sit out for 2 days (per instructions). After having them a week, they've perked up and became more full. I guess they just need time after being in the air. They are softer now but your head doesn't sink thru it. They are actually nice and soft to the touch as well.

On the thin side....
Color: White, Size: King (Pack of 2)
These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.
Color: White, Size: Standard (Pack of 2)
These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.

⭐⭐⭐⭐☆ Comfortable pillows with good support
Color: White, Size: Queen (Pack of 2)
I purchased the EIUE Hotel Collection bed pillows (2 pack) looking for something comfortable and supportive, and overall they’ve been a good addition to my bed. The pillows arrived well packaged and fluffed up nicely after opening. They feel soft but still provide decent support for sleeping. I’m mostly a side and back sleeper, and these pillows have worked well without feeling too flat. They hold their shape better than I expected and don’t require constant fluffing during the night. The fabric feels smooth and breathable, which helps keep them comfortable. My only small downside is that they’re slightly softer than what I personally prefer, but that really comes down to personal preference. Overall, these are comfortable, good-quality pillows that offer nice support and value for the price. I’d recommend them if you’re looking for hotel-style pillows that are soft yet supportive.
