Tayda's 1590A is its own casting rather than a relabelled Hammond, and we carry measured figures for both.

It runs a little larger than Hammond's in all three directions. On an enclosure this small the margins are already tight, so check anything sitting close to a wall before reusing a layout.

The drilled face, with the inside of the wall and the corner screw bosses as dashed hidden lines, and two sections cut on the centrelines showing the wall and the casting draft. Drawn from Tayda's dimensioned sheet, so it agrees with the figures below it. The top edge is rolled on castings like this one, shown here but not dimensioned.

Figures are read from Tayda's own drawing for this casting, the same data the editor and the comparison tool use. Tayda publishes no CAD, so these are measured from the sheet rather than derived from a model.

How thick are the walls?

The 1590A's walls are 2 mm thick. Like every diecast enclosure it also carries a casting draft: each wall leans out by 0.9 mm from the drilled face to the open rim, so the enclosure measures 39.5 × 93.9 mm at the rim and 37.8 × 92.2 mm across the face you drill. Worth knowing when a part seats against the inside of a wall, and why a caliper reading depends on where you take it.

What fits inside?

The internal cavity measures 33.8 × 88.2 mm at the face, and the screw bosses in each corner reduce the usable flat area for a circuit board to about 25.6 × 80 mm. To check a specific board, put its dimensions into the enclosure comparison tool's fit checker, or place the whole layout in the editor, which knows each component's real footprint and warns when something clashes with a wall or a boss.

1590A drill template

The Stompbox Layout editor has the 1590A as a built-in preset. Place your holes on it, and it prints a true-size PDF drill template with the enclosure outline, every hole position and a ruler to verify your printer's scale. Free, no download, runs in the browser.

Printed at 100% scale it works as a drilling template: tape it to the enclosure, centre punch each mark, then drill. Our guide to hand drilling a pedal enclosure walks the whole job, bit sizes included.

Nothing to tape down, nothing to slip, and it wraps the sides so the jacks line up. The editor makes one from your own layout, for the exact enclosure you picked, $29.

How the 1590A compares

Enclosure External at the rim Drilled face Depth Usable flat area
1590A (Tayda) 39.5 × 93.9 mm 37.8 × 92.2 mm 27.8 mm 25.6 × 80 mm
1590A (Hammond) 38.5 × 92.6 mm 37.1 × 91.2 mm 27 mm 25.6 × 79.7 mm

1590A vs 1590A

The 1590A is 0.7 mm narrower, 1 mm shorter and 0.8 mm shallower than the 1590A. The largest relative difference of the Tayda castings, on the enclosure with the least room to give. Re-check clearances rather than assuming.

1590A FAQ

What are the dimensions of a 1590A enclosure?

A Tayda 1590A measures 39.5 × 93.9 mm × 27.8 mm externally at the open rim (1.56 × 3.70 in). The drilled face measures 37.8 × 92.2 mm, and the usable flat area inside the walls and corner screw bosses is about 25.6 × 80 mm.

How thick are the walls of a 1590A?

The 1590A's walls are 2 mm thick, with a casting draft of 0.9 mm per side from the drilled face to the open rim.

Is there a drill template for the 1590A?

Yes. The free Stompbox Layout editor includes the 1590A as a preset and prints a true-size PDF drill template of your layout, with a ruler to verify print scale.
