Schlage S10D Jupiter (JUP) Grade 2 Tubular Lock

The Schlage S10D is the ANSI F75 passage function lever set from the Schlage S-Series light-duty commercial line, paired here with the Jupiter (JUP) lever design. Passage function means both levers are always unlocked, always free to operate, with no keyed cylinder. Use it on interior corridor doors, office tenant passages, closets, and any door that needs a commercial-grade lever without any locking mechanism. Grade 2 ANSI A156.2 Series 4000 certified, UL listed on fire-rated assemblies up to 3 hours. 

What Is the Schlage S10D Jupiter

The model code breaks down as follows: S = S-Series (Schlage's light-to-medium duty commercial lever line), 10D = passage function (ANSI F75, both sides free, no keying), JUP = Jupiter lever design. The Jupiter is one of five lever styles in the S-Series lineup alongside Saturn, Flair, Neptune, and Athens, and it's a rounded, slightly curved architectural lever that reads equally well in commercial and high-end residential settings. The S-Series is positioned below Schlage's ND-Series (Grade 1 heavy duty) and AL-Series (Grade 2 medium duty), so this is the right spec for interior passages and light-traffic openings where a full Grade 1 lever would be overkill and budget matters. If you need a keyed function in the Jupiter lever style, order the S40D (entrance), S51 (entrance with deadbolt), S70 (classroom), S80 (storeroom), or S170 (privacy).

S-Series Lever Styles (Jupiter vs Saturn vs Flair)

The Schlage S-Series ships in five architectural lever designs and you can match any function to any lever. For a more angular straight-line aesthetic, order the S10D Saturn passage variant instead. For a more traditional rounded look, the S10D Flair (FLA) is the right pick. All three (Jupiter, Saturn, Flair) are non-handed and use the same S-Series chassis, so the only real choice is aesthetics and how the lever feels in the hand. Price is identical at $195.00 across Jupiter, Saturn, and Flair in the S10D passage configuration.
