Door Closer, Concealed Jamb, Brass and Mild Steel, Perko

Product Details

Is the Perko concealed jamb closer suitable for my door weight?

Yes, for light to medium use. This model is intended for doors with a weight of up to 50 kg. If your door is heavier than this, you will likely need a different closer specification to achieve reliable closing performance.

Will this closer work with rising butt hinges?

No, it is not suitable for doors fitted with rising butt hinges. Using it with rising hinge types can prevent correct operation and may affect how the closer controls the door movement.

What opening angle can the closer handle?

It supports an opening angle up to 180 degrees. This makes it suitable for many interior swing door layouts where the door needs to open widely, while still maintaining controlled closing.

Is the closer for left hand or right hand doors?

It is available for DIN left or right fitting. Check whether your door is left hand or right hand before ordering so the closer suits the way the door swings and mounts correctly.

What finish is available and does it suit satin chrome hardware?

The product is supplied in satin chrome, making it a good match for common satin chrome architectural ironmongery. This helps the closer blend in with the rest of your hardware rather than standing out visually.

Is a buffer included with the 931.90.414 model?

No, the buffer is not supplied. The closer requires a separate buffer, so you will need to order the buffer separately to complete the installation.

What is included in the box for installation?

Fixing screws and fitting instructions are included. You will have the fasteners and guidance needed to mount the concealed closer correctly, which helps make installation straightforward for competent fitters.

What is the forend made from?

The forend material is brass. Brass components are commonly used in door hardware for strength and durability, supporting dependable operation over time.
