Backset ve Kapı Kalınlığı Tablosu 2026: Yayımlanan 589 Model Gerçekte Neyi Karşılıyor

Yedek bir kilidin önceden işlenmiş bir kapıya oturup oturmayacağına iki sayı karar verir: backset ve kapı kalınlığı aralığı. Burada yayımlanan kataloğumuzun gerçekte ne taşıdığını (broşürden alıntı değil, kayıtlardan sayılmış olarak), inç karşılıklarını, ölçüm yöntemini ve backset olmadığı hâlde onunla sık karıştırılan tek ölçüyü bulacaksınız.

Pirinç Kapı Donanımı 2026: Hangi Pirinç, İçinde Neden Kurşun Var ve Kıyı Projelerine Karar Veren Tek Arıza Türü

“Masif pirinç” farklı davranan bir alaşım ailesinin adıdır; en önemli fark, alaşımın çinko kaybına (dezinsifikasyon) dayanıp dayanmadığıdır. Bu sayfa kapı donanımında kullanılan pirinçleri sıralar, çoğunda neden kurşun bulunduğunu ve düşük kurşunlu alternatiflerin maliyetini açıklar, dezinsifikasyonu ve DZR pirincin gerçekten gerektiği yerleri anlatır, pirinci bronzdan ayırır ve kendi kataloğumuzun ne yayımladığını sayar.

Kapı donanımı hacimle değil ağırlıkla sınırlanan bir yüktür. Kendi sevkiyat çalışma tablomuzdan hesaplandı: medyan koli yoğunluğu metreküp başına 614 kg'dır; bu da 40 ayaklık bir konteynerin yeri bitmeden taşıma kapasitesinin bittiği noktanın üzerindedir. High cube yüzde 15 daha fazla hacim sağlar ve bu yük için hiç fazladan donanım sağlamaz.

Dimensional Interchangeability 2026: The Seven Dimensions That Decide Whether a Lock Drops In, and How Many We Publish

"Is it interchangeable?" is answered by seven dimensions, and two of them are the ones almost nobody publishes. This page lists them in the order they cause failures, explains why matching the backset is not enough, sets out what to send a factory when you want a drop-in for a discontinued lock, and counts how many of our own 258 lock products publish each dimension, including the one at two per cent.

Door Closer Mounting 2026: Regular Arm, Top Jamb, Parallel Arm and Slide Track Compared

The same door closer performs differently depending on where it is mounted, and the mounting is usually chosen on site by whoever is holding the drill. This page compares the four standard arrangements on the three things that matter (mechanical efficiency, projection into the opening, and vulnerability) explains why a parallel arm can cost you a power size, and sets out which side of the door each one lives on.

Door Closer Power Size 2026: EN 1154 Sizes 1–7, A156.4, and How to Pick One from the Door

A door closer is specified by a power size, and the power size is derived from the door (its leaf width and its mass) not from the opening or the building type. This page sets out the EN 1154 size ladder with the leaf widths each covers, how the ANSI/BHMA A156.4 approach differs, the three adjustments that are not the power size, and the accessibility constraint that overrides all of it.

Door Hardware HS Codes 2026: Headings 8301 and 8302 Decoded, and Where the Six Digits Stop

Almost every product in a door hardware catalog classifies under one of two HS headings: 8301 for locks and keys, 8302 for mountings and fittings. This page sets out the subheadings under each, names the four that are most often got wrong (door closers, keys shipped separately, parts, and furniture versus building fittings) and explains exactly where the internationally agreed code ends and your own country's begins.

EN 1125 or EN 179 in 2026: Panic Bar or Emergency Lever, and the One Question About People That Decides It

Two European standards cover escape hardware and they are chosen by who uses the building, not by how important the door is. This page explains what separates EN 1125 from EN 179, gives the occupancy test that decides between them, decodes the classification digits, lists the three mistakes that produce a non-compliant opening, and states what our own exit range does and does not hold.

EN to ANSI/BHMA Cross-Reference 2026: What Maps, What Does Not, and Why

Specifiers ask for a conversion table between EN and ANSI/BHMA door hardware standards. What exists is a scope map, not an equivalence: the two systems classify different properties, and a product certified to one carries no automatic claim under the other. This page sets out which standard covers which product family on each side, what each one measures, and the four places the mapping genuinely breaks.

Exit Device Outside Trim 2026: Every Trim Function Compared, Dogging Rules, and Why the Bar Is Never the Decision

An exit device has two halves and only one of them is a decision. The bar inside always lets people out; the trim outside decides who gets in, whether the door can be held unlocked during business hours, and whether the opening still complies in a fire. This page compares every outside trim function, sets out the dogging rules including the one that is absolute on fire doors, and counts how many of our own fifteen trims publish their function.

This page lists the components that must be rated, explains the difference between EN 1634-1 and UL 10C / NFPA 252 including the hose stream test that only one of them has, sets out what a certificate actually covers, and states plainly which of our own products do and do not carry a fire rating today.

Hinge Grades and Hinge Count 2026: EN 1935 Grades 1–14, ANSI/BHMA A156.1, and How Many a Door Needs

Two questions decide a hinge specification: what grade, and how many. EN 1935 answers the first with grades 1 to 14 tied to a tested door mass; ANSI/BHMA A156.1 answers it with a weight class and a frequency. Neither answers the second, which is governed by leaf height and mass. This page sets out both ladders, the count rule, and the three failure modes that come from getting the count right and the grade wrong.

This page explains what a blank and a profile are, separates open from restricted from patented keyways, is precise about what each one stops and what it does not, explains why a patent expiring changes the security of a building that was specified years earlier, and lists what a buyer has to decide before a master key system can be cut.

Master Key Hierarchy Planning 2026: The Levels, What Cross-Keying Really Costs, and How to Leave Room for the Building You Will Have

This page sets out the hierarchy, explains why every master level and every cross-key consumes capacity from a finite pool, and gives the questions to answer before a single cylinder is cut.
