Great Replacement for the NLA G 3121 Roller
Our house here in Flagstaff was built in 1998, the builder used Better-Bilt windows, which have aren't the greatest but are still in good shape today in 2022. However, one of the rollers on a sliding window began to fail, and the replacement part from Prime Line, G 3121, is no longer available. By comparing measurements, it appeared that this product, the G 3158, might serve as a replacement. It has the same 5/16" roller diameter, and is 3/8" wide. It differs in that it has two steel grooved rollers, compared to the original part having a single flat brass roller.Problem is that the G 3158 has a plastic tab you can see in the pics that the G 3121 lacks. All that was required was to cut the tab off with a coping saw, and it's a perfect replacement. Works better than the original roller! So, if you're searching for a G 3121, try one of these.

No one else makes it that I know
Like the title said, it’s the best because I don’t know who else makes it. It fits perfectly though. Fixed my 30 years old window!!

Not as described.
Nylon and steel wheels look like they would work well on a standard raised rail aluminum track. The wheels are not flat as listed in the title, they are grooved wheels designed for rolling on a raised track like on a sliding glass door.

Worked
Got the job done. The plastic is a bit soft.

Inferior pieces of junk
These wheels are smaller in diameter when compared to the wheels I'm replacing. These wheels barely rise above the nylon housing.After replacing the old worn out wheel rollers with these, the window was even more difficult to move.
