Customer Questions & Answers

Does the 22.5" product width include handrails and mounting hardware?

Asked by: Belton
The KARINA staircase kit is complete with a handrail for one side and all the mounting hardware. There is an optional 2nd side handrail kit available if your installation requires a handrail on both sides. Most installation of this model are against a fixed wall which is the reason there is only one side handrail included in the standard kit.

How large does the opening in the ceiling have to be? ? x?

Asked by: Bossie
The opening in the ceiling should be at least 26" wide to avoid a pinch point of the handrail against the opening. The running length of the opening should be at least at least 58" to allow for 6' 6" of headroom clearance when walking up and/or down the staircase.

Customer Reviews

Karina Black Modular Staircase Kit is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Perfect solution for limited space This is a well made, very handsome stair system. Be mindful of the fact that it will take some considerable time, manipulation and assembly skills to put together, especially if you do a curved stair system like I did. Video is very helpful to watch, written directions leave a little to be desired. Definitely not a 1 person project, Be careful with railing template for drilling alignment along outside stair edge (hole placement needs to be straight and equidistant to edge at exact depth to fit snug), and if you are curving your stairs, be prepared to improvise a bit and recalculate your rail heights along curve. Take time to get organized and mass assembly minded, there are many nuts, bolts, washers and set screws to deal with and between 5 to 9 holes to drill per stair. Connecting the "steel spine" of the stair and establishing your riser heights is not difficult but that portion of assembly is somewhat awkward and unwieldy ... but very possible with 2 strong folks. Patience + diligence = great results!

Rated 4 out of 5 by from Overall product quality is good, pleased with purchase. The stairs are attractive and sturdy. They take up min. amount of space and are quite functional. My wife and I did a lot of research to find something that would satisfy the need to access our loft while maintaining a small foot print in our living room. The Karina stair kit fills this need. Only bad commit is the instructions are terrible. U Tube video of other customers installations helped greatly.
