01 / THE FOUR EDGES↖ ↗ ↙ ↘
FREE FLOW. CLEAR REFERENCE.
A circular-gate flow, with diagonal reference points.
The familiar feel of rolling, rotating, and changing direction.
We added four diagonal detents to that familiar flow.
Physical stops at the diagonals provide tactile reference points, bringing the clearly defined directional control of a square gate to your fingertips.
Select an arrow to explore the four diagonal reference points.

FEEL.
01 / GOLD BODY
Designed low, finished in gold.
The low-profile body is a defining feature of the CrazyDongpal Pro.
The Edge Pro adds a new presence through the contrast of a gold-plated body and a black mounting bracket.
02 / DIAGONAL DETENTS
Through every rotation, corners you can feel.
Physical stops are provided at all four diagonal directions.
The detent depth and shape were balanced to feel natural to players accustomed to circular-gate operation.
03 / OMRON SWITCH
Let the corners come through naturally.
From the previous Gersung switches to OMRON.
The switch action was made smoother so that the gate corners and diagonal detents can be felt more naturally.

02 / LOW PROFILEMORE ROOM TO FIT.
A lower body, more room to fit.
A low-profile body designed with case clearance in mind is an important feature of the CrazyDongpal Pro. The Edge Pro continues that design approach.
Fit depends on internal case height, mounting-bracket position, and space for wiring.

A DIFFERENT FEEL, FROM THE INSIDE.
For a clearer reference, start with the switches.
OMRON V-152-1C25 · This arrangement illustrates four switches of the same model.
OMRON× 4 SWITCHES
Gate and switches, working together.
The lever was tuned around the operating characteristics of OMRON switches so that switch resistance does not dominate the feel, allowing the gate corners and detents to come through naturally.
A little shorter. Closer to the feel of direction.
From 51mm on the original CrazyDongpal Pro to 43mm on the Quadruple Edge.
The grip is 8mm shorter.
The grip shape and length were developed with both square-gate feel and familiar Korean-lever grip techniques in mind.
The clear green grip and matching dust cover create a coordinated look above the gold body.

The displayed lengths of 51mm for the CrazyDongpal Pro and 43mm for the Quadruple Edge omit decimal places. The 8mm difference is based on these two displayed values and does not refer to overall lever height or shaft length.
05 / THE WHOLE BALANCETUNED AS ONE.
RETURN. TRAVEL. WEIGHT.
Changes to each part, one balanced feel.
From a lightweight acetal actuator to a steel actuator.
The change in switches was considered together with return-to-neutral characteristics and the overall balance of the lever feel.
Shaft length and weight, actuator mass, and switch operating force were adjusted together. The design prioritizes how the parts feel together over individual components.

Shaft length and weight
How movement is transmitted from your hand.

Selected with both switch action and neutral return in mind.
03

An operating feel that works with the gate reference points.
ACTUATOR / TWO VIEWS

The actuator is the internal part that operates the switches. Neutral return and lever feel also vary with the tension rubber, grip, and installation.
06 / PRO → EDGE PROA NEW CHARACTER.
A familiar name, a new operating character.
More than a simple upgrade to the original Pro,
this is a new option designed to combine the strengths of circular and square gates.

LOW PROFILE / 5-PIN INTERFACE
From mounting clearance to connector orientation.
A low-profile body with a 5-pin connection.
Check your arcade stick clearance and wiring so you can focus on the feel of the lever.
Disconnect power before checking the orientation of the PCB and cable connection. If replacing a lever that uses 8-pin wiring, install the 5-pin lever cable supplied with the Quadruple Edge Lever.
03 / Test inputs
After assembly, use the game input display to check up, down, left, right, diagonals, and return to neutral. If only the up direction registers and the other directions do not respond, flip the 5-pin cable connector at the lever over by 180 degrees and reconnect it.
Mounting requirements and compatibility may vary with the internal construction of your arcade stick.

The small details that complete the Edge.
Explore the cable, dust cover, fasteners, and wrench supplied with the product. Read the included manual before assembly.
The positions of the washer and spring washer determine whether the shaft is locked against rotation or allowed to rotate freely.
A / Rotation locked
Keep the shaft from rotating.
Screw → Spring washer → Washer → Shaft
B / Free rotation
Allow the shaft to rotate freely.
Screw → Washer → Spring washer → Shaft
Read both sequences from the screw head toward the shaft. Disconnect power before assembly and refer to the diagrams in the manual below.

Appearance and manufacturing notes
The gold-colored body may have uneven contours or ripples commonly caused by the molding process. These are not product defects. The glossy gold-colored finish can make these areas more noticeable.
The paint finish on the steel mounting bracket may be uneven in color. Friction during assembly can also rub off the paint.
Minor scratches or dents may also occur during manufacturing. The manufacturer does not classify these as defects when they do not affect functionality. (Exceptions apply when there is a serious appearance flaw beyond what is normally found on this product.)
