User questions & answers

Question:	Can it be used to jump start a car parked at a garage
Answer:	Yes, I did. Mine was a one piece fiberglass tub and shower. A sawsall with a new blade cut the tub like butter. Be sure you have a vacuum for the dust handy.
Question:	What's the exact voltage on 24V maintenance
Answer:	No, my husband cut it by himself. There was a cutting pattern and directions to follow. Our tub is fiberglass. My husband does most repairs and projects
Question:	Has anyone charged a battery with this by plugging into 120v outlet on a generator (rather than home power
Answer:	Inserting or removing the panel is easy. You just drop it into place and secure with two bolts. The bolts have large, easy-to-grasp knobs. If the person can open screw-top medicine bottles, then they can manipulate the bolts. The removable panel is lightweight plastic.
Question:	Is this item waterproof
Answer:	If the leak is with the slide-in side panel, make sure you have tightened the big knobs at the top securely. Otherwise, you might need to re- redo the caulking. I ordered a second tube of caulk from the manufacturer. It is difficult to caulk the bottom edge and I did this several times.
Question:	Could you provide a data sheet of this item #offgridsolarspecialists
Answer:	A tub mat or bath mat is usually an extension of a towel program, and used specifically right outside the tub to absorb water following a shower or bath. A bath rug, however, serves multiple purposes. From a design standpoint, a bath rug can make a significant difference in the look of your bathroom.Mar 10, 2015 The Difference Between Bath Rugs and Bath Mats - InnStyle https://www.innstyle.com › blog › 2015
