Every project carries a long list of door functions. A hotel floor might include guest room entries, bathrooms, closets, and back-of-house openings, each requiring a different function. A multifamily building multiplies that across hundreds of units. The function on each door must be right, because it determines how the opening is used and how the hardware performs over time.
The harder part is keeping the design consistent while the functions change. When functions are specified one opening at a time, the hardware often fractures along the way: one look on the entry door, another in the bathroom, something else on the closet. The goal is to match the right function to every opening while carrying a single lever, rose, and finish across the entire project.
A Quick Orientation
Passage door hardware is for doors that don’t lock. Privacy hardware locks from the inside, typically with a thumb turn or push button. Entry functions provide keyed security from the outside. The more useful point for specifiers is what comes next: the function determines which platform makes sense, and the platform determines how the hardware holds up after years of daily use.
Passage and Privacy: Where Most Openings Live
On most hospitality and multifamily projects, bedroom and bathroom doors make up the majority of openings. These are passage and privacy applications, and they’re where tubular hardware usually earns its place. Closet doors work differently. They don’t latch, so they use single dummy levers that operate like a pull while matching the levers on every other door.
The T600 Series fits standard ANSI 161 door preps and is built on a heavy-duty interlocking chassis for reliable performance and straightforward installation. Latch options are matched to the application, with the 1SC commercial latch meeting ANSI/BHMA Grade 2 cycle standards, along with medium and residential grade options for projects with different use and budget profiles. That flexibility lets a specifier assign the right passage or privacy latch to each opening without changing the look of the hardware.
The T700 Series solves a different problem. Its small-rose trim uses a custom door prep so interior passage and privacy doors can match the appearance of mortise hardware on the entry doors nearby. The functions differ, but the hardware reads as one design.
Sliding and pocket doors need passage and privacy solutions too. The SL6 Series provides recessed, space-saving privacy locking for pocket doors. The SLT600 and PD800 tubular latchsets offer passage and privacy functions on standard ANSI 160 preps, and the EP6 edge pull handles non-locking passage pocket doors. Sliding door hardware can be finished to coordinate with the levers on hinged doors, so these openings stay part of the same design language.
Entry and Security Functions: Where Performance Matters Most
Unit entries, back-of-house, and common areas carry the highest security and cycle demands on a project. These openings call for locksets built to a higher standard.
The M500 Series mortise lock is ANSI Grade 1 UL-rated and available in dozens of functions, including electrified options for access control integration. That range lets a project standardize on a single mortise platform across entries, offices, and back-of-house openings as requirements change from door to door. In hospitality, guest room entries use lever trim sets adapted for leading hospitality electronic lock systems.
Because thumb turn styles, roses, and escutcheons can be coordinated across platforms, the entry hardware can share its look with the passage and privacy doors around it.
Matching Functions to the Space
Each project type has its own pattern of functions, but the principle stays the same.
In hospitality, guest room entries use access control lever trim sets, bedroom doors use passage T600 or T700 latchsets, closet doors use single dummy levers, bathroom pocket doors use the SL6, and back-of-house doors use the M500. In multifamily, unit interiors rely on tubular passage and privacy hardware with latch grades matched to budget and use, while corridor and common area doors use mortise locksets. In Class A office environments, private offices often need privacy or office functions, while conference rooms and interior doors lean toward passage hardware.
Across all three, the thread is one lever family carried through every function. With more than 225 lever designs and a broad finish range, the hardware on a closet door can match the hardware on the front entry, even though the two do completely different jobs.
Specifying With Confidence
Function selection goes more smoothly with the right documentation. FR International provides door prep templates for every product series, along with cut sheets and product literature that support submittals and installation. Levers comply with ANSI A117.1 accessibility requirements, and ADA compliance documentation is available for inspection and approval.
When an opening falls between categories or a function question comes up late in the project, FR International’s technical team can help confirm the right function and platform before it becomes a field problem.
