# (caf) Important - Not for exterior use unless both Rail and Balusters are made of PVC. Otherwise, inadequate water drainage may create premature rot. Flat-Top Bottom Rails will not look as traditional nor as substantial as our sloped-top style, but they do allow easier installation of Balusters on stairs because compound notching of Baluster bottoms is eliminated.
Our Flat-Top Bottom Rail has two interlocking pieces. This provides easy installation, hidden hardware, and substantial, traditional styling! Just screw top piece of Railing into bottom of the Balusters. Then, using our pre-drilled holes, screw bottom piece of Railing into place. This two-piece format also permits easy
Kickspace Blocks are used to support longer Balustrade sections at an appropriate height above the porch floor. Use one Kickspace Block evenly spaced under every 4 or 5 feet of Bottom Rail.
Also see Interior Bottom Rails in our Interior Stair Parts section. A motor freight surcharge may be required on small orders for longer lengths. If so, we will advise before finalizing your order.
Note: We are currently unable to obtain Western Red Cedar at reasonable prices in the quality and lengths we require for Rails. We suggest you consider Cypress or AZEK® Brand Cellular PVC (synthetic wood) if you want to upgrade from Poplar for exterior use.
