Use and Care Manual
FIBERGLASS LADDER TECHNICAL MANUAL
             1
INTRODUCTION
Fiberglass  ladders  were  developed  after  years  of  design,  testing  and  field  use  as  a 
non-conductive  tool.  For  the  best  performance  and  greatest  life  expectancy,  fiberglass 
ladders must be maintained and handled with greater care than wood or aluminum ladders.
This  manual  outlines  fiberglass’  unique  characteristics,  test  results,  handling 
procedures, maintenance, and recommended modes of use.
While  the  test  data  is  of  greatest  interest  to  the  technically  minded,  it  is  important  that  all 
users understand the nature of fiberglass ladders and the proper maintenance procedures.
Recommendations for specialized use, maintenance, storage, transport, or other needs are avail-
able from Werner Co. upon request.
