Klein Tools 51603 – Frequently Asked Questions
1) What trade sizes of EMT does the Klein Tools Iron Conduit Bender cover?
Three sizes are offered, each a separate bender: 1/2-inch EMT (part 51603), 3/4-inch EMT (51604), and 1-inch EMT (51605). A bender head is size specific, so if you run more than one trade size on a job you need the matching bender for each. All three are for EMT (thinwall) conduit.
2) Can I use this Klein bender on rigid or IMC conduit instead of EMT?
No. It's cut for EMT (thinwall) only, and the shoe geometry and take-up are matched to EMT wall thickness and outside diameter. Rigid and IMC have a larger OD for the same trade size and need a bender head sized for rigid, or a hydraulic/mechanical bender.
3) What stub height and take-up should I figure for the 1/2-inch Klein bender?
On the 1/2-inch EMT bender the centerline bend radius is 4 inches with a 4-5/8 inch centerline radius figure and a 5 inch stub-up height reference. Use those numbers when you deduct for a stub so the bend lands where your layout mark is.
4) What is the Angle Setter feature on this Klein conduit bender actually doing?
Angle Setter creates hard stops at 10, 22.5, 30 and 45 degrees, and those stops are already adjusted for conduit spring back. You pull to the stop instead of eyeballing the mark, which is what makes repeat bends match on a run of offsets. It's patent pending on the Klein iron bender.
5) Does this conduit bender come as a complete tool with the handle?
It ships as a full assembly, head and handle together, with a 38 inch handle (96.5 cm) and an overall height of 43.1 inches. No separate handle purchase, and nothing to thread on before the first bend.
6) If the handle or hook gets damaged, can I get parts instead of a whole new bender?
Yes, replacement parts are published for this bender: 51427, 51608 and 51611. That matters for a shop standardizing on one bender across crews, since a bent handle doesn't retire the head.
7) Is a hand bender like this enough for a commercial job, or do I need a mechanical bender?
For 1/2, 3/4 and 1 inch EMT a hand bender is the normal tool, and this one covers those three sizes for commercial, residential, industrial and MRO work. Once you move to larger EMT, or to rigid and IMC, you're into mechanical or hydraulic benders instead, since this head is EMT specific in those three trade sizes.
8) What bend angles are marked on the bender head?
Cast markings cover 10, 22, 30, 45 and 60 degrees, plus the matching offset multipliers, so you can lay out offsets and saddles off the head without a chart. The markings are bold cast symbols for lining up back-to-back and saddle bends quickly.
9) Does the conduit slip or twist in this bender when you pull a bend?
The interior hook surface is shaped to keep the conduit from rolling or twisting through the pull, which is what keeps an offset in plane. The wide foot pedal gives you a stable place to put your boot while you pull, so the head doesn't walk on you.
