How to install Middle Atlantic ERK-40-R-EXT3

  • Verify compatibility: Ensure your rack supports rear-depth extensions and that you have access to the rear mounting points and doors intended for reuse.
  • Prepare the rack: If your doors are currently in place, remove or loosen them only as needed to align the extension frame with the rear rails and mounting points.
  • Position the extension: Align the ERK-40-R-EXT3 extension with the rear of the rack, matching mounting holes and edges to the existing frame for a secure fit.
  • Secure the frame: Use the appropriate mounting screws or hardware specified for your rack model to attach the extension firmly to the rear rails, ensuring there is no wobble and that the frame sits flush with the cabinet.
  • Reinstall doors: Reattach the existing doors (or reinstall the doors supplied with your rack) to maintain a cohesive appearance and proper door clearance with the extended depth.
  • Route cables and power: Utilize the electrical and cable pass-through knockouts to organize cables, power feeders, and data lines behind the door panel. Label and route cables to minimize congestion and maximize airflow.
  • Test and finalize: Close the doors, verify clearance, and power on equipment to confirm proper fit and operation. Make any minor adjustments to cable routing as needed.

My all time fave sunscreen!
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
This is the best sunscreen! Does NOT burn my eyes like 95% of other sunscreens do. Does NOT break out my sensitive skin, or my sister who has the most sensitive skin ever! It goes on smoothly due to its nice texture, does NOT feel greasy. Wears great under foundation as well. Thank you Coola for such a great formula at an affordable price. I have turned so many 'sunscreen snobs' into fan favorites of this as well. If you haven't tried it, you should!

good for non-white skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
Moisturizing, non-sticky, works for my sensitive skin. It's transparent and doesn't leave a white cast on my light brown skin. Smallish size is good for travel and purse. It's a little shiny; wish it came in matte.

Very effective
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen for your face. It doesn’t feel oily. It doesn’t stay white on your skin. It absorbs and it really protects it nicely. I put it on every morning before I walk my dog in the sun and I’m out for normally at least an hour so it’s a really nice sunscreen and I would definitely give it a try.

Lightweight, clean, and effective — worth the repurchase
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
This is my go-to daily sunscreen. It’s lightweight, non-greasy, and absorbs quickly without leaving a white cast. I love that it’s made with clean ingredients and doesn’t irritate my sensitive skin. The white tea scent is subtle and fresh. I’ve repurchased this several times now — it’s one of the few sunscreens I actually enjoy using.

Great replacement for my discontinued Epionce sunblock
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I really hate it when companies discontinue great products, and even though it cost a fortune, I loved the Epionce mineral sun block for faces. When I realized it was gone, I looked at the Coola line because I like their other products. Found this face sunblock for $32 (this could be 1/3 of the Epionce, certainly 1/2) and have used it for the past few weeks playing golf. So far, so good! I'm not noticing any color, certainly no burn. No irritation, and the scent is quite mild, only noticeable when it's first applied (IMO, and I'm pretty sensitive to scents). I really like that Coola has the Hawaii reef-safe designation, which I think is very important for all sunscreens, even when we're not going swimming in the ocean. As a friend pointed out to me once, even if you don't swim in the ocean, you go home and take a shower and all those chemicals wash down the drain and make their way eventually through the system, so might as well just not use them in the first place! Yes, it's more expensive using products like this, but IMO it's worth it. I also wear sun sleeves these days so I don't have to use as much sunscreen when I'm out on the golf course. Editing this to say that this product has avobenzone, which is actually not so great and may be banned in Hawaii by next year. Hmm. Guess I'll keep searching!
