Description

Alaks MO97 Overhang Cap | Curved Sash Cap for AH59 System

The MO97 overhang cap is one of the key finishing components in aluminum door hardware, designed to cover the ends of curved mullion profiles in the AH59 hinged system. This part, also known as overhang cap or mullion end cap, is mounted at the end of the mullion (overhang) profile and, in addition to creating a neat and professional overall look, helps improve sealing and protect the profile end.
In the AH59 hinged series, there are two different designs for the central mullion profile of double leaf doors:
• Curved (Softline) profile – code 760
• Flat profile – code 10137
The MO97 overhang cap is specifically designed for the curved profile and is precisely matched to the curvature of this section.

What is the MO97 Overhang Cap and What Does It Do?

The overhang cap is a finishing piece installed at the end of mullion/overhang profiles and performs several important functions in the door structure.
By covering the end of the profile, it ensures:
•   Complete coverage of profile edges
•   A clean and professional appearance at the meeting point of the sashes
•   Prevention of dust and contamination entering the inside of the profile
•   Improved sealing at the end of the section
The MO97 model, with its curved design, is especially suitable for doors that use Softline or rounded profiles.

Technical Specifications of MO97 Overhang Cap:

•   Part Name: Overhang Cap
•   Technical Code: MO97
•   Design Shape: Curved / Convex
•   Compatible System: AH59
•   Compatible Profile Type: Curved profile – code 760
•   Material: Scratch and abrasion resistant plastic
•   Application: Covering profile ends, completing door appearance, assisting sealing

Compatibility of MO97 Cap with Different Systems:

The MO97 overhang cap is originally designed for the AH59 system, but in some projects, depending on the profile used, it can also be applied in other systems such as AH45 or AH56.
However, its best performance is achieved when installed with the curved profile of the AH59 series, because its dimensions and curvature are engineered exactly according to this section.
Difference Between MO97 and MO37 Caps
In the AH59 system, there are two types of overhang caps for the central mullion of double leaf doors, each designed for a specific profile type:
MO97:
•   For curved profiles
•   Compatible with profile code 760
•   Curved / Softline design
MO37:
•   For flat profiles
•   Compatible with profile code 10137
•   Flat design
Using the wrong model can cause level differences or incomplete fitting of the cap onto the profile.

Advantages of Using the Curved MO97 Overhang Cap:

Using the proper overhang cap in aluminum hinged systems significantly improves both performance and final appearance of the door. The MO97 model offers the following benefits:
•   Perfect coordination with curved profiles
•   A smooth, continuous, and unified appearance
•   Elimination of sharp edges at the profile end
•   Contribution to better sealing of the door structure
•   High resistance to impact and environmental stresses
•   Stability under direct sunlight and outdoor exposure

Material Quality and Production Process:

The MO97 overhang cap is manufactured from scratch and abrasion resistant plastic with high resistance to environmental conditions.
It is produced through a precise manufacturing process to ensure:
•   Fully accurate dimensions
•   Tight, play free installation inside the profile groove
•   No deformation under temperature changes
•   Long term preservation of its curved shape

Key Points When Selecting an Overhang Cap:

To select the correct cap, you must pay attention to the type of profile used.
•   If your project uses curved (Softline) profiles, the MO97 model is the best choice.
•   If the profile has a flat surface (Flat), the MO37 model must be used instead.
A mismatch between cap and profile type can lead to:
•   Improper fitting of the part
•   Level differences on the visible face
•   Reduced sealing performance
•   Lower aesthetic quality of the door or window

The MO97 overhang cap is a specialized component designed to complete the structure of aluminum doors in the AH59 series with curved profiles. Its arched design creates a unified and professional look at the meeting point of the sashes, while protecting the profile end and enhancing sealing performance. The use of durable material and precise production makes this cap stable against environmental conditions, temperature variations, and direct sunlight.When implementing aluminum door systems, the use of standard hardware and high quality finishing components is not merely a choice but a professional necessity.
