Frequently Asked Questions

Rotary latches engage around the striker with no exposed tongue to pry. Combined with shielded strikers, through-bolted installation and optional cylinder locks, the forced-entry resistance of the door line exceeds that of standard quarter-turn hardware.

Yes — provided compression system is specified for it. Gaskets harden in cold and relax in heat; we match latch compression travel to your gasket material across the temperature range at specification stage, so the IP target holds year-round.

Standard models ship quickly from stock programs; customized samples are delivered in 20–35 business days from confirmed drawings. Free STEP/DWG files are available within one business day so your design team can start immediately.

M = double protection inside and outside the door. The SLC3-2578 without M protects the outside only.

If washdown spray reaches both sides of the door, order the M. If only the outside sees washdown, the 2578 covers it at lower cost.

Deep door frames, offset striker positions, or long cam travel behind reinforced frames. Send a drawing if you are unsure; we check the geometry against your frame.

Same protection level and load; the difference is locking reach (69.4 mm vs 48/54.7 mm). Match it to your frame depth.

Replenishment of an existing 2575 program: order this model. New design: we will quote the 2578/2579 generation unless you have a reason to stay on 2575.

Yes, the mounting system is designed for thin sheet: nut to 17 N·m, screw to 8 N·m. For panels over 5 mm, use the SLC3 series (1–15 mm).

A1 SUS304 for dry areas and cost-driven projects; A2 SUS316 for splash zones with chlorine-based chemistry.
