Essential Crank Casement 86
The American crank-out casement, built in aluminum: a familiar rotary operator and hinge geometry, so it reads and works the way a US crew and a US homeowner expect, with the thermal numbers of a modern thermally broken frame. Twin-casement and push-out configurations, three screen types, EPDM spacer.
Configure your unit, then request a quote — we price it and reply, usually within one business day.

Low-E1 / E2 / E3 coatings, laminated and tempered build-ups available. We recommend the coating for your climate zone.
Full RAL range on request; the twelve most-ordered colours are listed. Powder coat or anodised.
No price is shown because every unit is made to order. You will get a written quote for exactly this configuration.
Overview
The American crank-out casement built in aluminium on an 86 mm platform: a rotary operator and side hinges that swing the sash outward left or right, with an awning variant hinged at the top and a fixed lite in the same frame for combinations. It reads and works the way a US crew and a US homeowner expect, which is the point of it — the familiar operator, on a modern thermally broken frame.
The choice inside this product matters more than the choice between it and its neighbours. It is built in two configurations with materially different envelopes: the twin casement carries up to 220 lb of sash at 2 m2, with a largest unit of 84" by 36" or 72" by 48", on Roto and Hoppe hardware; the push-out casement carries 132 lb at 1.3 m2, with a maximum of 42" wide or 60" high, on Maco and Hoppe. Specify the wrong one and the size you drew is not available. Against its wood-clad counterpart, the 163 crank casement, this is the aluminium build on a much shallower section — the same operator family, a different material and a different depth of wall.
Frame and sash are aluminium at a 2 11/16" by 2 11/16" section with a profile wall thickness of at least 1/16". Interior sash visible width is 3 1/16" in both configurations. The sealed unit sits on an EPDM spacer and the glazing pocket takes 1 7/8" of glass, so the frame is sized for a real triple-glazed build-up rather than only a double. The outswing casement envelope is drawn to a maximum height of 7 feet at a width under one metre; the awning variant is limited to 6 feet wide, 5 feet high and 60 kg of sash, and at its 1-foot minimum height the catalogue restricts the opening to 20 degrees.
Multi-point locking is standard, which is what keeps the larger sashes operating smoothly on one crank. Three screens are offered on the push-out configuration — a fixed removable fly screen with high-visibility mesh, a retractable screen, and a casement screen. Divided lites use duplex glazing bars, 28 mm on the interior and exterior faces with a spacer between them, so the division reads as separate panes from both sides. Standard glazing is 1" double pane, 6 mm plus a 12 mm argon cavity plus 6 mm, or 1 5/8" triple. In the NFRC directory the fixed record for this series certifies a 0.26 U-factor double-glazed and 0.17 triple; the casement record certifies 0.45 double and 0.36 triple. Those certified figures govern.

The platform number is a nominal frame depth in millimetres — contact us for the exact measured section before you detail the opening.

Mounting and frame options
The frame type decides the rough-opening detail, the flashing and how much of the existing wall has to come out. Four are available; tell us the wall build-up and we will specify which one your opening needs.
The standard new-construction frame. The flange laps the sheathing so the unit sets and seals in one operation.
A 1 3/8" flange is available where the cladding build-up needs the extra reach.
Installs over an existing aluminum window frame, so the stucco exterior is left intact. No cutting back and repatching.
Available on selected window types — ask us which of your openings can take it before you price the stucco work.
For full removal, when the existing frame is rotten or damaged and has to come out entirely.
Sets into the existing rough opening, and arrives with the through-the-jamb holes pre-drilled and the screws supplied.
Straps fix to the frame, which lets the unit sit anywhere in the depth of the wall cavity rather than at a fixed setback.
Installs from the interior, and works for both new construction and replacement.
Full CAD details for any of these are available on request for your wall assembly.
Factory-joined combinations for large openings
Multi-unit combinations are joined in the factory and delivered as one assembly, so the joint is made under shop conditions instead of on a scaffold. The joining mullion is 1 1/8" (28 mm) wide and comes in three reinforcement grades, chosen by the height of the window it has to carry. The system is covered by a US patent.
| Suggested window height | Joint width |
|---|---|
| up to 9 ft | 1 1/8" (28 mm) |
| 9 to 11 ft | 1 1/8" (28 mm) |
| 11 to 13 ft | 1 1/8" (28 mm) |
Combinations arrive partly or fully assembled depending on size and shipping method. Tell us the opening and we will confirm which grade your height needs and how the unit will be split for transport, before you price the crane time.
How large combinations are joined →Where a window has to serve as an escape route, three dimensions matter at once — clear width, clear height and clear area — and meeting two of the three is not enough.
Awning units and single tilt-only units cannot be used as escape windows at all, because the sash itself obstructs the opening. If an opening is designated for egress, it needs an operator that swings or turns clear.
The figures above are the manufacturer’s minimums for the product and are NOT a code citation. US residential egress under IRC R310 is a different set of numbers — 5.7 sq ft net clear opening, 24" minimum height, 20" minimum width — and your jurisdiction’s adopted code governs, not this page. Send us the opening schedule and the address and we will confirm in writing which units satisfy the code that applies to you.

NFRC certified performance
Certified figures from the NFRC Certified Products Directory — the source a U.S. building department will check. This window is certified separately as a fixed lite and as an operable lite, so both are shown: the operable sash carries the hardware and the operating joint, which costs a little thermal performance.

Bay and bow assemblies
Both are built from the units on this page rather than being separate products, so the finish, glazing and hardware you specify here carry straight through into the assembly.
Units set at an angle to project out from the wall, which turns a flat elevation into a seat, a deeper sill or a reading corner. Built from 3 to 6 casement or tilt-turn units, each of which can be fixed or operating — so you can put opening lights only where you need ventilation.
Four or more units connected in a gentle outward curve rather than faceted angles. Reads softer than a bay and pulls light in from a wider arc. Available with casement, tilt-turn or picture windows.
Size and performance figures on this page are for the individual units. The structural limits of a specific assembly — how wide, how many lights, what header is needed above it — are confirmed by the factory against your opening, and we get that in writing before it is quoted.
Exterior finish
The exterior is extruded aluminum cladding, which is why the finish schedule matters more here than the colour chart on a vinyl window: it is a powder coat on structural extrusion, not a surface tint.
19 finishes are available in total, including three pearlescent. Twelve are named here; ask us for the rest, or for a custom colour match.
Swatches are indicative only — reproduced from print, shown on your screen. Specify by RAL number, and ask us for a physical sample before you commit an elevation to a colour.
