Heavy-Duty Commercial Crossbar Panic Hardware with Key-Controlled Exterior Thumbpiece | ANSI/BHMA Grade 1

The Arrow S1805-RR-4 Rim Exit Device is a heavy-duty commercial panic device designed to provide dependable emergency egress, secure mechanical latching, and controlled exterior entry for commercial and institutional door applications.

Part of the Arrow S1800 Series, this Grade 1 exit device features a traditional horizontal drop-bar design, single-point rim latching, and an architectural US4 Satin Brass (606) finish.

The S1805-RR-4 is specifically configured for Right-Hand Reverse (RHR) door applications and features a Thumbpiece Function, allowing exterior entry through a compatible key-controlled thumbpiece arrangement while maintaining free emergency exit operation from the interior.

Unlike modern rectangular touch-bar panic devices, the Arrow S1800 Series uses a traditional round crossbar supported by mechanical operating arms. Depressing the horizontal crossbar retracts the rim latchbolt, allowing occupants to exit without using a key.

Manufactured to ANSI/BHMA A156.3 Grade 1 performance standards, the Arrow S1805-RR-4 combines heavy-duty mechanical construction, a stainless steel latchbolt, and classic architectural styling for commercial offices, institutional facilities, government buildings, and renovation projects.

Important: This listing is for the specific S1805-RR-4 configuration: Rim Exit Device, Thumbpiece Function, Right-Hand Reverse, and US4 Satin Brass.

Traditional Drop-Bar Crossbar Design

The Arrow S1805-RR-4 features the classic horizontal crossbar style commonly found on commercial and institutional doors.

The operating crossbar extends across the interior face of the door and connects to the mechanical latch chassis through forged operating arms.

When pressure is applied to the crossbar, the mechanism retracts the rim latchbolt, permitting immediate emergency egress.

Crossbar Construction & Operation

• Traditional horizontal round crossbar

• 1" tubular crossbar diameter

• Brass, bronze, or stainless steel tubing construction within the S1800 Series

• Forged brass and stainless steel operating arms

• Mechanical single-action exit operation

• 4-1/2" crossbar projection in neutral position

• 2-3/4" projection when depressed

• Heavy-duty commercial construction

The traditional design makes the S1805-RR-4 particularly suitable for buildings where matching existing architectural panic hardware is important.

Key-Controlled Thumbpiece Function

The S1805 designation identifies the Arrow S1800 Series thumbpiece-function rim exit device.

The thumbpiece function provides a mechanical method of controlling exterior entry using a compatible key-operated locking arrangement.

When unlocked, the exterior thumbpiece can be operated to retract the latchbolt and permit entry.

When locked, exterior thumbpiece operation is restricted while the interior crossbar continues to provide emergency egress.

Thumbpiece Function Benefits

• Key-controlled exterior access

• Convenient thumbpiece entry when unlocked

• Independent interior emergency egress

• Suitable for commercial entrances requiring controlled access

• Mechanical operation without electronic access-control equipment

• Traditional architectural appearance

• Compatible with designated Arrow S1800 Series thumbpiece trim

Important: Thumbpiece function differs from Exit Only. Confirm the exact supplied trim, cylinder, and keying requirements before ordering.

Heavy-Duty Rim Latching System

The Arrow S1805-RR-4 incorporates a surface-mounted rim latch that engages a compatible strike installed on the door frame or approved center mullion.

Unlike a surface vertical rod device, which uses upper and lower latching assemblies, this device secures the door at a single rim-latching point.

Depressing the interior crossbar retracts the stainless steel latchbolt for immediate exit.

Rim Latching Features

• ANSI Type 1 rim exit device

• Single-point mechanical latching

• Stainless steel latchbolt

• 5/8" latchbolt throw

• Mechanical crossbar release

• Right-Hand Reverse configuration

• Compatible frame or mullion strike required

• Suitable for properly prepared commercial doors

The correct strike and installation arrangement must be selected for the existing door and frame conditions.

Right-Hand Reverse (RHR) Configuration

The RR designation identifies the Arrow S1805-RR-4 as a Right-Hand Reverse device.

This configuration is intended for a compatible right-hand reverse-bevel, outswinging commercial door.

Handing Information

• Manufacturer handing code: RR

• Door handing: Right-Hand Reverse

• Common abbreviation: RHR

• Factory-designated handed configuration

• Not universally reversible

• Opposite handing requires a compatible LR configuration

Important: Verify handing, hinge location, and door swing before ordering. Left-Hand Reverse and Right-Hand Reverse versions should not be treated as interchangeable.

US4 Satin Brass Finish – 606

The US4 Satin Brass finish provides a warm, brushed architectural appearance suitable for commercial and institutional interiors.

Unlike highly polished brass, Satin Brass offers a softer finish that complements traditional and contemporary commercial door hardware.

Finish Details

• Manufacturer finish suffix: 4

• Architectural designation: US4

• BHMA finish number: 606

• Finish description: Satin Brass

• Appearance: Brushed brass

The US4 finish coordinates with matching commercial hinges, pull plates, locksets, door closers, and architectural trim.

Allen-Type Mechanical Dogging

The standard non-fire-rated Arrow S1800 Series uses an Allen-type mechanical dogging arrangement.

Dogging allows authorized personnel to hold the operating crossbar in its depressed position, keeping the latchbolt retracted for convenient push/pull operation.

Common Dogging Applications

• Commercial entrances during business hours

• High-traffic office and retail openings

• Non-fire-rated commercial doors

• Locations requiring temporary push/pull operation

• Buildings where repeated latch engagement is undesirable

Fire Door Warning: Mechanical dogging must not be used to hold the latch retracted on labeled fire door assemblies requiring positive latching. The S1805-RR-4 is a standard non-fire-rated configuration.

Heavy-Duty Commercial Construction

The Arrow S1800 Series is designed for commercial applications requiring reliable mechanical operation and traditional architectural styling.

Construction Features

• Pressure-formed non-ferrous alloy chassis

• Cold-drawn architectural metal chassis and end covers

• Forged brass and stainless steel operating arms

• 1" diameter tubular crossbar

• Stainless steel rim latchbolt

• Allen-type mechanical dogging

• Handed operation

• US4 Satin Brass architectural finish

This construction makes the S1805-RR-4 a practical option for commercial door maintenance, renovation projects, and replacement of existing crossbar-style panic devices.

Product Specifications

Thumbpiece Function vs. Exit Only

The Arrow S1800 Series includes several operating configurations.

Arrow S1801 – Exit Only

The S1801 provides unrestricted interior emergency egress without an exterior thumbpiece operating function.

This configuration is suitable for commercial doors where routine exterior entry is not required.

Arrow S1805 – Thumbpiece Function

The S1805 provides key-controlled exterior thumbpiece operation.

When unlocked, authorized personnel can retract the latchbolt using the exterior thumbpiece. The interior crossbar remains operative for free emergency egress.

Important: The S1801 and S1805 have different exterior access functions and should not be treated as interchangeable models.

Rim Exit Device vs. Surface Vertical Rod Hardware

Arrow S1805 – Rim Exit Device

• Single-point rim latching

• Compatible frame or mullion strike

• No vertical rod assemblies

• Traditional horizontal crossbar

• Thumbpiece function

Arrow S1705 – Surface Vertical Rod Exit Device

• Top and bottom vertical rod latching

• Dual-point mechanical engagement

• Traditional crossbar operation

• Thumbpiece function in the corresponding configuration

These devices require different door preparations and are not direct substitutes.

Standard vs. Fire-Rated Configuration

The Arrow S1805-RR-4 is the standard non-fire-rated configuration.

Standard S1805
