Safety Benefits


Sentry Covers have been tested to meet the American Society for Testing and Materials (ASTM) standard for safety covers as outlined in ASTM F1346-91:


Weight Support

Sentry Covers meet ASTM static load requirements.


Perimeter Deflection

Sentry Covers pass all ASTM perimeter deflection test requirements, which demonstrate that all openings are strong enough to prevent objects from passing through the cover.


Surface Drainage

Sentry Covers have passed ASTM surface drainage tests which are designed to prevent a dangerous amount of water collecting on top of the cover.


Proper Labeling

All Sentry Covers include proper warnings and warranty information such as described in the ASTM standard.


Energy & Heating Benefits


In addition to safety, your pool cover offers energy savings such as:



 Conserve water by reducing the amount of make-up water needed by 30-50%


 Swim earlier and longer in colder climates with better heat retention–reducing in pool heating costs by up to 70%


 Reduce the pool's chemical consumption by 35-60%


Reduce cleaning time by keeping dirt and other debris out of the pool


By reducing the evaporation on a heated pool, the average owner could save as much as $4,330 per year in energy, water, and chemical costs



Better Design & Materials


Sentry Covers is dedicated to using better materials and fabrication methods to improve visual aesthetics, reduce maintenance and increase product life.




Custom Printing:

We believe the pool cover industry needs more than stock colors. The entire cover is now your canvas. From custom colors and gradients to patterns, monograms and high-resolution photography. We’ll help you design a cover that fits your personal design preferences.



Hidden Webbing:

A drawback of standard, automatic safety cover fabrication is that it results in a visible seam along the cover perimeter. This means the webbing color has to also match the pool cover color in order to achieve the desired aesthetic. Because the cover and webbing are two different materials, color matching is not always perfect.


Our SentryWeld™ fabrication technique uses a welded seam to reduce the webbing to a narrow section that is hidden inside of the rope guide track. This gives the pool cover a seamless appearance and eliminates the need to match fabric colors. This is especially important if you're investing in a custom printed cover with artwork spanning edge-to-edge.



Proprietary Rope Design that Lasts 30% Longer

A rope with too much stretch or elongation will reduce the performance and lifespan of your safety cover. That's why we specifically designed our safety cover rope with a thicker fiber core tested to last 30% longer than standard covers.
