you should note that that while the ECL 500 is compatible with almost every wire spine available

Do you work with a lot of wide-format
documents? Do you like the look and feel of wire binding? If so, you
should consider the Renz ECL 500 Electric Ring Wire Closer. Let's take
a look at this device so you can see what it has to offer.

• Binding width and capacity. The ECL
  500 has a very impressive binding width of 19.7 inches which is
  equivalent to 50 centimeters. Because of its incredible width, you can
  use this device for both large and small documents, including those
  printed on tabloid-sized paper that measures 11 x17". Also, this device
  is pretty fast. When you use it, it will be possible to bind up to 400
  books in just one hour.
• Wire compatibility.
  This machine is compatible with just about any type of wire spine you
  could want to use including Spiral-O and twin-loop supplies. You can
  use both 2:1 and 3:1 pitch supplies in any size. So whether your
  document is thin and you need a 3/16" spine or your book calls for a
  large 1-1/2" one, you'll be able to use this machine to close it. Also,
  you can use calendar hangers with this device. Not all closers have
  this feature.
• Safety features. Safety is
  always an important consideration when you're working with any type of
  machinery. The ECL 500 is a very safe device to use because it has an
  integrated safety circuit that keeps your fingers free from cuts and
  other injuries.
• Size and construction. This
  is one of the larger wire closers available. With dimensions of 21"
  (length) x 25" (width) x 8" (height), this machine will take up a fair
  amount of room so it's not ideal for cramped workspaces. The ECL 500
  weighs almost 90 pounds, so you'll need to be very careful when moving
  it. Also, this machine has all-metal construction which makes it
  extremely durable and perfect for use in high output environments such
  as copy rooms and print shops.
• Ease of use. The
  ECL 500 is very easy to use, even if you've never used this type of
  device. It only takes a few seconds to adjust the settings so you can
  work with spines of different sizes. All you need to do is turn the
  knob on the right side of the device. Also, this machine comes with a
  foot pedal that will help you get your work done faster because your
  hands will remain free.

Finally, you should note that that while the ECL 500 is compatible with
almost every wire spine available, you cannot use other binding
elements with it such as plastic combs and color coils. Also, this is a
standalone device. It doesn't have a paper punch, so you'll need to use
another machine to prepare your documents. (Using pre-punched paper is
another option. It will also help you save some time.)

Overall, the Renz ECL 500 is an excellent choice if you frequently work
with wide-format documents and need a wire closer. It's binding width
is excellent and it's great you can use the full range of wire binding
elements. If this sounds like the machine for you, be sure to take a
