Klein Tools 935CSEL – Frequently Asked Questions

1) Will the Klein 935CSEL combination square hold itself on a steel panel or strut without clamping?
Yes. The 935CSEL uses rare-earth neodymium magnets in the body, so it sticks to ferrous surfaces like enclosure sides, strut, steel studs and panel backs and stays put while you scribe or read the level. That is what makes one-hand layout possible on a vertical panel. It will not hold on aluminum enclosures, PVC or wood, so you still need a clamp or a free hand there.
2) What does the conduit layout template on this electrician's square actually do?
It lets you size and center conduit work without a second tool. The template finds center on EMT knockouts and identifies conduit diameters, so you can lay out box knockouts and conduit runs directly off the square. The reverse face of the ruler carries an electrical panel schedule template for planning conduit and wiring entries into a panel.
3) How fine are the markings on the Klein 935CSEL 12-inch square, and are they inch or metric?
Graduations are 1/8 inch and 1/16 inch, and the scale is SAE (inch) only, no metric. The markings are deeply etched into the stainless ruler rather than printed, so they do not wear off with abrasion or solvent on a job site.
4) Is the blade on this Klein square removable, and can it be used as a standalone ruler?
Yes, the body detaches from the 12-inch stainless ruler, so you can pull the blade off and use it as a straight rule or a depth gauge, then reattach it for squaring. The ruler itself is stainless and rustproof; the body is aluminum with a powder coat finish.
5) Can I use this square to set a miter saw or chop saw for cutting strut and conduit?
That is one of its intended uses. The aluminum body has precision machined 45 and 90 degree edges, so you can register it against the fence and blade to set a miter saw or table saw to a true angle. A bubble vial with a large window and reinforced housing is built in for checking level and plumb on the same tool.
6) Is this the right square for a machinist or is it built for electrical work?
It is built for electrical layout. A standard combination square gives you 45 and 90 degree edges and a rule, and the 935CSEL does that too, but the added features are the conduit layout template, the panel schedule template, the magnets for holding on steel enclosures, and the built-in scriber. If your work is bench machining or fine woodworking, the electrical templates are dead weight. For panel, rough-in and conduit work they are the point of the tool.
7) Do I need a separate scribe or marker with the Klein 935CSEL?
No. A stainless steel scriber is integrated into the tool, so you can mark metal enclosures, strut and conduit for precise layout without carrying a separate scribe. Nothing else is required to use the square.
8) How big and heavy is the Klein electrician's combination square for pouch carry?
It weighs 10.6 oz (299 g) and measures 12 inches on the long dimension, 5.16 inches, and 0.75 inches thick, so it drops into a tool pouch or the back pocket of a bag without adding real weight. The 12-inch ruler is the governing length for storage.
9) What model number should I order for the Klein electrician's combination square?
The part number is Klein Tools 935CSEL, the 12-inch electrician's combination square. It ships as a single configuration, so there are no length, finish or graduation options to specify on the order.
