What is the difference between S1 and S2 mounting springs?
The difference between S1 and S2 mounting springs lies in the application purpose. S1 springs are used in a hollow ceiling (e.g. plasterboard or wooden plates), while S2 springs are used in a concrete ceiling (e.g. concrete slabs or vaults).
Another difference between S1 and S2 springs is the way of placement.
S1 springs are ‘open’ – with the legs up – when they are placed into the ceiling. The legs then press down to fasten the spotlight.
S2 springs are ‘closed’ – with the legs down – when they are placed into the ceiling. The legs then press to the outside to fasten the spotlight. These S2 springs can also be used in a square hole.
