Carbine Ascot Tiebolt Classroom Leverset

Carbine Ascot Tiebolt Classroom Leverset Overview & Applications

Replacing worn hardware or pricing up a commercial building schedule goes much faster when your lock footprint matches existing door cutouts. Australian locksmiths and builders specify the Carbine Ascot Tiebolt Classroom Leverset because its internal springs, fixing bosses, and working clearances suit commercial offices, schools, hospitals, aged-care facilities, and fire-rated apartment entry doors (35mm to 45mm thick) requiring DDA lever compliance. Direct commercial drop-in equivalent for Lockwood 930/534 leversets, Dormakaba C100/C200, and Brava Commercial EA/EL series.

Pair this item with matching hardware in our Commercial AS 1428.1 Leversets range or check our AS 1428.1 DDA Accessible Door Hardware Hub. On commercial, strata, or rental upgrades, always follow the Australian Building Codes Board (ABCB) AS 1428.1 & AS 1905.1 Door Hardware Compliance.

Door Prep & Fitment: PA8012-L1 Commercial Tiebolt Leverset

Before ordering replacement hardware, run a tape measure over your existing cutout. When checking PA8012-L1 commercial tiebolt leverset on site, the PA8012-L1 retrofits standard 54mm circular door holes with anti-rotation tiebolt posts, 35mm-45mm knuckle clearance, <= 20N operating force, and a 70mm commercial backset latch (60mm optional). Matching your existing hole centres and backset lets you swap worn parts cleanly without patching timber.

3-Step Fitting Guide: AS 1428.1 DDA Compliant Lever Handle

Follow these three practical steps for AS 1428.1 DDA compliant lever handle so the mechanism lines up cleanly on the first pass:

1. Verify door handle mounting height is between 900mm and 1100mm above the finished floor level (AFFL) to satisfy AS 1428.1:2021.
2. Fit the 70mm (or 60mm) fire-rated tubular latch into the 25mm edge bore and secure the tiebolt chassis through the 54mm circular face hole.
3. Tighten the concealed rose mounting screws and confirm single-hand downward lever retraction with <= 20N force.

Build Quality & Standards: AS 1905.1 Two Hour Fire Rated Lock

Lightweight variety-store hardware quickly suffers from handle sag, surface pitting, or sticky latches under Australian sun and coastal air. The genuine PA8012-L1 features heavy-duty satin chrome or stainless steel AS 1428.1:2021 compliant returned lever assembly tested to 400,000 cycles and 2-hour fire-rated to AS 1905.1. Engineered around AS 1905.1 two hour fire rated lock, every internal spring and load-bearing surface is built to handle heavy daily foot traffic.
