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

The Arrow S1805-LR-32 Rim Exit Device is a heavy-duty commercial panic device designed to provide reliable emergency egress, secure mechanical latching, and convenient key-controlled exterior access.

Part of the Arrow S1800 Series, this architectural exit device features a traditional horizontal drop-bar design, a surface-mounted rim latch mechanism, and a polished US32 Bright Stainless Steel (629) finish.

The S1805-LR-32 is configured for Left-Hand Reverse (LHR) commercial doors 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 exit devices, the Arrow S1800 Series uses a traditional round crossbar supported by mechanical operating arms. Applying pressure to the crossbar retracts the rim latchbolt, allowing occupants to exit without using a key.

Manufactured to ANSI/BHMA A156.3 Grade 1 standards, the Arrow S1805-LR-32 combines durable mechanical construction, a stainless steel latchbolt, and traditional architectural styling for commercial offices, institutional buildings, renovation projects, and high-traffic commercial doors.

Important: This listing is for the specific S1805-LR-32 configuration: Rim Exit Device, Thumbpiece Function, Left-Hand Reverse, and US32 Bright Stainless Steel.

Traditional Drop-Bar Crossbar Design

The Arrow S1805-LR-32 features the traditional horizontal crossbar style commonly found on commercial and institutional doors.

The operating bar extends across the interior face of the door and connects to the mechanical chassis through two operating arms.

When pressure is applied to the crossbar, the latchbolt retracts and allows the door to open.

Crossbar Construction & Operation

• 1" diameter tubular crossbar

• Traditional architectural drop-bar design

• Forged brass and stainless steel operating arms

• Mechanical single-action release

• Approximately 4-1/2" projection with bar in neutral position

• Approximately 2-3/4" projection when depressed

• Heavy-duty commercial construction

• ANSI/BHMA Grade 1 performance

This design provides a practical replacement option for existing commercial openings where traditional crossbar hardware is preferred or required.

Key-Controlled Thumbpiece Function

The S1805 designation identifies the Arrow 1800 Series thumbpiece-function rim exit device.

This function allows controlled exterior entry using a compatible thumbpiece and key-operated locking arrangement.

When the thumbpiece is unlocked, authorized users can operate the exterior thumbpiece to retract the latch and enter the building.

When the thumbpiece is locked, exterior 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 free egress from the interior

• Suitable for commercial entrances requiring controlled access

• Mechanical operation without electronic access-control equipment

• Traditional architectural appearance

• Compatible with properly configured Arrow 1800 Series trim

Important: Thumbpiece function is not the same as Exit Only. The exact supplied trim, cylinder, and keying configuration must be confirmed when ordering.

Heavy-Duty Rim Latching System

The Arrow S1805-LR-32 incorporates a surface-mounted rim latch that engages a compatible strike installed at the door frame or approved center mullion.

Unlike vertical rod exit devices, which use upper and lower latches, this configuration provides single-point rim latching.

Depressing the interior crossbar retracts the latchbolt for immediate emergency egress.

Rim Latching Features

• ANSI Type 1 rim exit device

• Single-point mechanical latching

• Stainless steel latchbolt

• 5/8" latchbolt throw

• Mechanical crossbar release

• Left-Hand Reverse operation

• Compatible strike required

• Suitable for appropriately prepared commercial doors

The correct strike and mounting configuration must be selected for the existing door and frame conditions.

Left-Hand Reverse (LHR) Configuration

The LR designation identifies the Arrow S1805-LR-32 as a Left-Hand Reverse device.

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

Handing Information

• Manufacturer code: LR

• Door handing: Left-Hand Reverse (LHR)

• Factory-designated handed configuration

• Not universally reversible

• Opposite handing requires the appropriate RR configuration

Verify handing from the correct side of the door before ordering.

Bright Stainless Steel Finish – US32 / 629

The US32 Bright Stainless Steel finish provides a polished architectural appearance that coordinates with premium commercial door hardware.

Unlike satin stainless steel, which has a brushed surface, US32 features a bright, reflective finish.

Finish Details

• Manufacturer finish suffix: 32

• Architectural designation: US32

• BHMA finish code: 629

• Finish description: Bright Stainless Steel

• Appearance: Polished stainless steel

This finish coordinates with polished stainless steel hinges, door pulls, commercial locksets, push plates, and other matching architectural hardware.

Finish Note: US32 Bright Stainless Steel is different from US32D Satin Stainless Steel. Confirm the required finish before ordering.

Heavy-Duty Commercial Construction

The Arrow S1800 Series is manufactured for commercial applications requiring durable operation and traditional architectural styling.

Construction Features

• Pressure-formed non-ferrous alloy chassis

• Cold-drawn brass, bronze, or stainless steel chassis and end covers

• Forged brass and stainless steel crossbar arms

• 1" tubular operating crossbar

• Stainless steel rim latchbolt

• Allen-type mechanical dogging

• Handed operation

• Bright Stainless Steel architectural finish

The durable construction makes this device suitable for commercial door maintenance, renovation projects, and replacement of existing crossbar-style panic hardware.

Product Specifications

Thumbpiece Function vs. Exit Only

The Arrow S1800 Series includes different operating functions.

Arrow S1801 – Exit Only

The S1801 provides unrestricted interior egress without standard exterior operating trim.

This configuration is useful for commercial doors that do not require regular entry from outside.

Arrow S1805 – Thumbpiece Function

The S1805 incorporates a key-controlled exterior thumbpiece function.

Authorized personnel can operate the exterior thumbpiece when unlocked while the interior crossbar continues to provide emergency egress.

Important: The S1801 and S1805 serve different exterior access requirements and should not be treated as interchangeable products.

Rim Exit Device vs. Surface Vertical Rod Hardware

Arrow S1805 – Rim Exit Device

Uses a single rim latch that engages the door frame or an approved center mullion.

Arrow S1705 – Surface Vertical Rod Exit Device

Uses upper and lower vertical rod latching for compatible commercial door configurations.

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

Standard vs. Fire-Rated Configuration

The Arrow S1805-LR-32 is the standard non-fire-rated configuration.

Standard S1805
