What is the difference in between the LA SLM and LA original?
LA SLM (LA1120) and LA original (LA1) are both made for single or extension ladder type 2 and type 3.
You can check out their tech guides in their own page.
The LA SLM is an all steel construction: strong, solid, sturdy, and compact. It has the same great quality and features as the LA original.
The LA original is made of steel and aluminum, so it is lighter than the LA SLM.
