What are the differences in head rails?
Head rails are located at the top of the blind and are made from either plastic or metal material. They supply the support system for the blind and house the components which allow for tilting, raising and lowering the slats. The plastic head rails are very inexpensive but are highly susceptible to structural fatigue and sagging if additional support brackets are not added. The metal head rails are made from steel or aluminum and offer the highest quality support system on the market today. It is highly recommended by this writer to avoid the plastic due to its inferiorities. The metal rails come in a high profile (2″x2.25″) or low profile (1.5″x2.25″) dimensionally. The high profile rail has greater strength than the low profile if all other factors are equal but both rails seem to function well in the capacity that they fill.
