Isomat Spreaders |
|
| Isomat Spreader Sections feature an integral 'tail', so that the Spreaders can be tapered at the
outboard ends without welding. Please Note that Early versions of Isomat Spreaders had similar dimensions but had no
'tail' - all Spreaders were supplied with a cut and welded taper, and a welded tip.

| For replacement Spreaders and Parts,
determine which Spreader you have by measuring the Spreader Section. Click on individual Spreader Sections, below, to see hardware and Parts commonly used with those Sections. See also
