A screwed ledger or cleat is free but leaves a row of holes and has to be rebuilt every course. Panel clamps grip the Z-flashing, leave no holes, and move course to course, but they support the panel at only two points and depend on having flashing to grip. The EZpanl kit nails a row of hooks to the wall, rests the panel across the hooks beneath it, leaves the fastener behind the finished panel rather than in the finished face, and mounts independently of the flashing. Which is right depends on your panels and your volume.

A note on what we took out of this table. This comparison used to carry a cost-per-support-point row: roughly $12 for us against roughly $50 for a clamp set. We removed it because it flattered us. Dividing each package price by the number of pieces in it treats one hook as equivalent to one clamp, and it is not. A set of two clamps is one deployment on a panel. How many hooks a given sheet needs depends on the current EZpanl instructions, and we do not publish a hooks-per-sheet figure, so the number on our side of that division was never real. The prices above are simply what each one sells for. PacTool listed the SA907 Z-Clamp at $99.99 for a set of two on its own product page, checked 2026-07-30; some retailers list it below that.
Where each one wins
Screwed ledger
Best for a one-off panel or a repair. Free, familiar, and you already have the scrap. The cost shows up when you repeat the build-and-patch cycle across a whole job.
Panel clamps
Clean and quick when you have flashing to grip and you are hanging shorter panels. The limits are that two points can let a long sheet sag or pivot between them, and no flashing means nothing to clamp.
EZpanl hooks
Built for full walls and production siding, and for bare sheathing where there is no flashing yet. A row of support hooks rests the panel across the hooks beneath it, sets a repeatable line, and avoids the exposed ledger-board holes and patching associated with common temporary-cleat methods.
The rule for all three
No support tool changes what a compliant install requires. Panel siding is a minimum two-person job, and the manufacturer sets the fastening, flashing, and clearance schedule.
