Viking Electronics 258817 Rough-In Box for K-17XX Series Entry Phones

Overview

The Viking Electronics 258817 is the dedicated rough-in enclosure for the K-17XX series of analog video entry phones — a single-box solution that handles structural mounting, cable management, and environmental protection for one of the tougher-duty Viking Electronics entry phone families on the market. If you're roughing-in a new commercial door station or retrofitting an existing opening, this box eliminates the improvised mounting hardware that causes callbacks.

Built from 14-gauge 316 stainless steel, the 258817 is sized to accept the K-17XX phone module and its integrated 420-line analog camera, 125kHz proximity card reader, and telephone-line-powered electronics — all of which are exposed to whatever the installation environment throws at them. The rough-in box is the structural backbone that makes an IP66-rated, -40°F to 150°F entry station possible in a single flush installation.

Key Features

• 14-Gauge 316 Stainless Steel Faceplate: 316 SS is the marine/coastal grade — it resists chloride pitting that eats 304 SS in salt-air environments. At 14 gauge, it withstands physical abuse without deforming the camera or card reader alignment. Relevant wherever vandalism or coastal exposure is a design criterion for your door entry station.
• IP66 Environmental Rating: Ingress protection at IP66 means sustained high-pressure water jets and complete dust exclusion won't compromise the enclosure. Rain-driven installations, loading dock overhangs, exterior vestibules — all appropriate. IP66 does not cover submersion; skip this for below-grade or flood-prone recesses.
• Operating Range -40°F to 150°F with Up to 100% Condensing Humidity: Most commercial entry hardware fails below 0°F. The K-17XX family — and this enclosure — is rated to -40°F, which covers unheated northern Minnesota parking structures and outdoor arctic-climate installations without a separate heater kit. The 100% condensing humidity rating means coastal fog and daily temperature cycling won't cause water ingress failures.
• 420-Line Analog Camera with 2.1mm Conical Pinhole Lens: The integrated camera delivers 420 lines of horizontal resolution via a 2.1mm conical pinhole lens — an 80° horizontal / 100° diagonal field of view that captures a full door-width face shot at typical entry distances without being an obvious camera target. Sensitivity is 0.025 lux, adequate for a well-lit vestibule; this camera is not IR-compatible, so plan lighting for night use.
• 125kHz Proximity Card Reader, 26-Bit Wiegand Output: The onboard card reader operates at 125kHz and outputs standard 26-bit Wiegand — the most widely supported format across access control panels from HID, Lenel, Software House, and virtually every commercial access control system. Read range is 1.25
