"The fun part of fasttech's listings and how they word it, is trying to figure out what fits with what. FT's Dvarws are like little puzzles of wrong descriptions, as it seems.
These inserts seem to be for the DL version. The 0.8mm and 1mm (SKU 9727473) already listed for the 22mm should also fit the 24mm MTL one."![]()
The MTL FL inserts are shorter and will not fit in the DL FL.
AF inserts for the DL FL are longer in size and will not work in the MTL FL's.
The DL FL has a larger build area on the deck vs the MTL FL. The 22/24mm MTL FL's build area is the same size.
