Used baseboard questions

cchuc

I have a few sections of baseboard that I’ve removed while remodeling a basement and would like to reuse it. I need a couple end caps and a splice joint but can’t figure out who made these. Does anybody recognize the covers in the photos?
Also, the way these fin tubes were installed appears to be off by 90 deg. The folds on the fins are on the top/bottom rather than on the vertical edges. Seems to me this would kill the natural convection flow. The plastic pads are the right width for those folded edges but the brackets are wide enough to fit the long (unfolded) edges on the top/bottom. Is there a reason these would have been installed this way?
Based on some records it looks like these may have been installed early 90’s. They used gray PB pipe, which I’ve already added to the trash heap.
I greatly appreciate any help

Yes the fins need to be open top to bottom or no convection is possible. Judging by the plastic sliders they were not installed correctly.

maybe a name on it? maybe some series of slant fin. you can get aftermarket replacement covers. you can bend the joint cover out of steel or aluminum sheet metal. new baseboard is pretty inexpensive too.

Looks like Sterling Petit 7 baseboard.

I don't know what it is but I don't think it is Sterling.

I think a piece is missing, but the damper hinge looks like SlantFin. The end cap doesn’t look like the series 30. The end capes were more rounded.

maybe a lower model SF?

This is a Sterling petit 7 end cap

the petite 7 looks like a pretty good match, thanks yellowdog. Webb carries it so I’ll take a piece down to see if it matches up.
Hot rod, thanks for confirming the direction for the fins. Seems odd that the sliders are sized to set them that way. The open side is wider than the folded side and the slider fits snug on the narrower face. I’ll check with Webb for those too.
thanks for the help.

It looks like there is a little slot in the fins on the bottom for the slide to snap in to

Rotate the tube 90 degrees to facilitate convection vertical through the fins. At the lowest point in the system, add a first 3-way "T" outing to a 3/4 garden-hose threaded (and a ball valve) (for system cleanout), then a full-pass ball valve in-line, and add a second 3-way "T" outing to a 3/4 garden-hose threaded (and a ball valve). Because, at the lowest point, if you have a cast iron boiler, your system may accumulate iron oxide sludge, and that is sometimes too dense or heavy to clear out at the boiler end. so, with these two additional drainage options at the lowest point, you can send pressurized water to there in either direction to the lowest point to flush out the sludge. I figured this out when a radiator section froze this winter (under an open basement window used to provide fresh air to the boiler). Because of the sludge blockage, the expanding water burst the radiator copper tube at a weird place (at end of radiator section).

The plastic sliders are meant to be mounted vertical on the fins. This keeps them out of the air flow up thru the element.

Ok, I see it now in the cross section from the manual. The sliders on the sides work in pairs to allow them to carry the fins at the bottom. These were installed with 2 slides side by side, so I have most of what I'll need to do it the right way. Thanks for pointing that out.

Martial7, the boiler is a Bosch KWB35-3. I don't think they use cast iron in these things? There is a ball valve and drain near the bottom of the boiler if I remember correctly. Would that still be important to be able to clear heavy oxide residue from this type of boiler?
