Hardware Buying Guides

Choosing a window transmission rod for repeat purchasing involves the complete window system: the profile groove, handle, locking points, keepers and operating movement. Buyers searching for a window espag rod, espagnolette locking rod or multipoint lock drive rod may be describing related hardware, but the names do not establish that two parts are interchangeable. Use

A window espag rod transfers handle movement to the locking points along the sash. Buyers may call it a transmission rod, espagnolette rod, locking drive rod or multipoint locking rod. To match a replacement or approve an OEM order, record the complete interface: rod length, gearbox position, handle connection, mounting holes and locking-point locations. This

A replacement sliding door trolley needs to fit the sash pocket, run correctly on the rail and carry the intended load as part of the complete door system. A similar photograph, a “13 × 20” label or a heavy-duty description cannot establish those three conditions. This guide is for importers, hardware distributors and aluminium or

Specify a custom heavy-duty friction stay for a 20–80 kg sash project. Compare four-bar and two-bar designs, provide the window drawing and agree the fitting and test basis before an OEM quote.

A non-standard bearing for a door or window system is rarely identified reliably from one photo or a stamped bearing code. The bearing may be hidden inside a pulley, plastic wheel, metal housing, bracket or complete roller assembly. For B2B replacement and OEM programs, the safest route is to convert the existing sample and installation

A custom deep groove ball bearing RFQ should describe the application, dimensions, fits and acceptance criteria—not only ask for a “special bearing.” For importers, distributors and OEM equipment buyers, a clear specification shortens quotation time and reduces the risk of receiving a sample that fits the drawing but fails in the assembly. Start with a

Knowing how to install a glass door pull handle begins before the handle reaches the door. The installer needs an approved drilling layout, the correct handle pair or single-sided fixing arrangement, nonmetallic isolation components and a complete hardware kit matched to the glass thickness. This guide helps importers, distributors, door fabricators and project teams define

Standard glass door handle sizes are usually described with more than one number: overall length, center-to-center (C-to-C) mounting distance, tube diameter or section, projection and the glass interface. A buyer who sends only “600 mm handle” may receive the wrong drilling pattern even when the visible length looks correct. This B2B size guide organizes common

Compare fiberglass and ordinary stainless steel insect screens by construction, visibility and frame compatibility. Understand magnetic mounting, high-visibility mesh and the evidence needed for security or fire-performance requirements.

An 18×16 or 20×20 label does not fully specify a window screen. Learn how yarn diameter, opening size, finished fabric weight and roll dimensions affect sample approval and bulk purchasing.
