BTI49.5 is a castellated solid brass stair nosing insert.
The castellation design gives an ultimate slip resistance and using this as a retro fit stair nosing insert allows for a completely hidden fixing installation.

It also gives the option to have a different finish on the tread insert to the stair nosing, allowing for more design options, contrasts and effects!

Example photo shows a polished brass stair nosing with a satin brass tread insert.
SRV (Slip Resistance Value) is determined using the Pendulum 4S testing method.
This in conjunction with UK Slip Resistance Guidelines gives a reading of potential risk.
​The guidelines certify anything above 36 as a low risk potential.
