Metal fabricators are skilled professionals who design, cut, weld, shape, and assemble metal components to create various structures or parts. They work with many different metals and tools while also following blueprints.
Junction boxes have knockouts on top, bottom and sides. Top/bottom knockouts are 2 and 1-1/2 in - sides are 2, 1-1/2, 3/4 and 1/2 in. Photo shows box with components that may also be . A knockout for 1/2" conduit is 7/8", but the outside diameter of a 1/2" EMT fitting is about 3/4". 3/4" knockout is 1-3/32" (close enough to 1-1/8), . Sizes 1/ 2 " thru 6" per proposed revision to NEMA Engineering Bulletin No. 71, Aug. .

Pedestal (35" Ht. x 4" Wd. x 4" Dp.) Choose from our selection of junction boxes, including corrosion-resistant washdown enclosures, indoor enclosures, and more. In stock and ready to ship.Box knockouts are pre-measured to create perfectly sized openings for common conduit sizes, and each takes just a few seconds to remove. They can also be easily reclosed by knockout plugs and knockout seals later.
The sizing requirements for pull boxes, junction boxes, handhole enclosures, and conduit bodies exist to prevent conductor insulation damage. Those requirements are in 314.28, and they apply to all conductors 4 AWG . How do I know what size to order? The electrical industry has common conduit sizes. EKO’s are routinely made for these common sizes. However, EKO tools must be . Section 314.16 specifies the minimum volume size of junction boxes required for various types of electrical conductors. The volume size of a junction box is measured in cubic inches. It is determined based on the number and .
These regulations describe in detail the required junction box size, depending on the number and size of conductors and fittings enclosed within the box. You’ll need to calculate both box volume and box fill when determining .How To Find Exact Knockout Size For Conduit? Contractors appreciate panels and enclosures with knockout holes because they can install wires and conduits without making new holes. You don’t have to tolerate smaller knockouts. You can enlarge them to accommodate larger conduits.
Junction boxes have knockouts on top, bottom and sides. Top/bottom knockouts are 2 and 1-1/2 in - sides are 2, 1-1/2, 3/4 and 1/2 in. Photo shows box with components that may also be ordered separately. A knockout for 1/2" conduit is 7/8", but the outside diameter of a 1/2" EMT fitting is about 3/4". 3/4" knockout is 1-3/32" (close enough to 1-1/8), and O.D. of 3/4" fitting is roughly 1". So basically 1/8" for fudging around?Sizes 1/ 2 " thru 6" per proposed revision to NEMA Engineering Bulletin No. 71, Aug. 1976. Both rigid conduit and intermediate metallic conduit are threaded and accept couplings, nuts, and bushings et cetera directly.Pedestal (35" Ht. x 4" Wd. x 4" Dp.)

The sizing requirements for pull boxes, junction boxes, handhole enclosures, and conduit bodies exist to prevent conductor insulation damage. Those requirements are in 314.28, and they apply to all conductors 4 AWG and larger ( Fig. 1 ).
How do I know what size to order? The electrical industry has common conduit sizes. EKO’s are routinely made for these common sizes. However, EKO tools must be ordered for the actual size of the hole, not the conduit size. See conversion chart below: Form Up .
