Two HAT Collective E5 dynamic spring arms on one top-down mount, each for a screen of up to 11.3 kg and 32 inches. 267 mm of height adjustment, three rotation joints per arm, quick-disconnect VESA plates, clamp and grommet included for desks up to 38 mm, and HAT's 15-year warranty.
HAT Collective E5 Dual Dynamic
Two Screens, Each on Its Own Spring
The E5 Dual Dynamic puts two spring arms on one mount. HAT rates each for a screen of up to 25 lb (11.3 kg) and 32 inches, with 267 mm of height adjustment and three rotation joints, so the pair can be set edge to edge or at different heights and angles.
The photo shows HAT's polished finish in an open office; this listing is the white or black arm.
Set-Up
One Mount, Fitted From Above
Both arms share one top-down mount: a C-clamp or a grommet fixing, both included, on desks up to 38 mm thick, installed from above the desk with one tool that stores in the mount.
Rotation stops are set from outside each arm to 90, 180 or 360 degrees, and a tension indicator on each arm lets you set the spring to its screen before the screen goes on. The photo shows a black E5 Dual beside HAT's laptop holder, a separate accessory.
The Details
Five Things That Make It an E5
The mount, the quick connections, the tension indicator, the tilter head and the cable route. Detail photos show HAT's silver and polished finishes.
Top-Down Mount, One Tool
Clamp or grommet, fitted from above, with the tool stored in the mount.
Push-Button Quick Connections
HAT builds the E5 from 12 components joined by push-button connections.
Tension Indicator
Set each spring to its screen's weight before the screen goes on.
Quick-Disconnect VESA
Each VESA 75 / 100 plate releases, so screens change without tools.
Cable Management
Cables route along the arms and down the post.

Who It Suits
Two Full-Size Screens, Set Separately
Each arm carries a screen of up to 11.3 kg and 32 inches on its own spring, with 267 mm of height adjustment, so two people sharing a desk, or one person with two different screens, can set each one to its own height, angle and distance.
Send us both screen models on 02 9640 0642 and we will check the weights and your desk before you order.
E5 Dual Dynamic, White or Black
This Model
This listing is the HAT Collective E5 Dual Dynamic in white (E5-D2-WHT) or black (E5-D2-BLK), with C-clamp, grommet mount and quick-disconnect VESA adapters included. Choose the finish above. The photo shows the white finish.
Prefer the screens on a single bar with a handle to move both at once? See the E5 Dual Crossbar. For two lighter everyday screens, the E2 Dual costs less.
Why We Stock the HAT Collective E5 Dual
We stock the E5 Dual Dynamic because it puts two heavier screens on one desk fixing, each on its own spring, with quick-disconnect plates so a screen can be changed without tools. HAT builds it from 12 components joined by push-button quick connections.

Frequently Asked Questions
If each screen weighs no more than 11.3 kg without its stand, is no larger than 32 inches and has 75 or 100 mm VESA holes, it is within HAT's rating. Check the weights on the screen maker's specification sheet.
The E5 mounts from above with a C-clamp or through a grommet hole, both included, on worktops up to 38 mm thick. A grommet hole needs to be at least 57 mm across (HAT's cutsheet; its product page says 51 mm). If a beam or modesty panel sits at the back edge, call 02 9640 0642 before you order.
Here each screen has its own arm and moves on its own. On the E5 Dual Crossbar both screens sit on one bar on a single arm, with a handle to move the pair together.
The E2 Dual takes two screens of 1 to 9 kg up to 27 inches, with a 10-year warranty, for less. The E5 Dual Dynamic takes heavier and larger screens, adds quick-disconnect VESA plates and external rotation stops, and carries 15 years.
15 years. HAT Collective's published warranty covers E5 monitor arms for 15 years under normal use of a 40-hour, five-day week. Claims are handled by Chair Dinkum in Sydney on 02 9640 0642; full terms are on our warranty page.
