## Description

Reptology presents the Turtle Topper Extender Clips by PENN-PLAX. On its own, the Turtle Topper (Model #: REP600) can only fit most standard rectangular tanks up to 55 gallons and 13” wide. With these Extender Clips, you can now mount the Turtle Topper on rectangular tanks up to 55 gallons and 19.5” wide. You no longer have to worry about filament issues with wider tanks! In other words, these clips allow for mounting on wider tanks, up to 19.5” in width. The gallon capacity and other standard limitations still remains the same. These Extender Clips are Sold Separately from the Turtle Topper.Easy to Use: With the suction cup facing up and in, place the Extender Clip on the wall of an open tank, and then tighten the plastic screw by turning it clockwise. Repeat 3 more times, and you’re good to mount your Turtle Topper!Secure Mounting: When all 4 Extender Clips are mounted and aliened properly, the Turtle Topper sits comfortably atop the 1” suction cups, allowing your turtles to safely climb to the basking platform. At the end of each plastic screw is 0.75” swiveling back plate, making for the best possible fit against tank walls. Furthermore, each Extender Clip has a removable spacer at the bottom.Small & Sturdy: While the Extender Clips are optional and don’t come with the Turtle Topper, they’re always good to have on hand! For instance, if you’re changing tanks or moving to another house, you no longer have to limit yourself to 13” wide tanks! With the approximate dimensions of 1.5” (W) x 5.25” (D) x 3” (H) for each Extender Clip, storage is not an issue!Shop PENN-PLAX for All Your Pet’s Needs: PENN-PLAX is a manufacturer and distributor of top quality pet supplies, who specialize in creating excellent pet products for animals, both great and small.

Review: Fantastic product, Turtle loves it, works on a 20g tank too - Absolutely LOVE this product... would give it 6 stars if I could. No matter your current setup, no matter the size of your aquarium, this product will add 30% to 50% more swimming room for your turtle(s), because everyone else I know uses some sort of floating turtle dock that forces you to only partially fill whatever tank you have (plus some docks take up a lot of swim roon on their own account), while this product allows you to fill your aquarium nearly to the top (its actually kinda required because of the entry ramp). We have a 6 year old Yellow Bellied Slider of healthy size and our turtle has been thrilled ever since we added this to his 20-gallon aquarium (yeah, smaller then we'd like, but its much better now with this topper). He has a LOT more swimming room now then he had before because of the previous dock... well, basically the entire aquarium is free to swim in now... he LOVES the underwater platform, and has no problems climbing in or out of the basking area, which he loves because he can get totally 100% dry and bask in the warm lights all he wants now (and he goes back and forth a lot). I know most turtle owners have a 55 gallon tank which this is ideal for, but as a smaller tank owner (standard 25L x 14W x 18T), this is pretty much the only way you can pull off a smaller tank and not feel guilty about it. As the topper is about 17" long, a 20g tank owner will have about 8" left of space to work with... which for me was enough room to put a large filter and an aquarium light across the width of the tank (with the help of a stretched out wire coat hanger as added safety/support)... my turtle can actually use all 20g of the tank now for swimming, which probably puts him on par with a 40-50 gallon tank owner who's aquarium is only half-filled to support a standard floating dock. If there's a single negative to this product, its that no matter the size of your tank, you'll have to deal with whatever the 17" long topper itself doesn't cover, because the nature of the topper means you have to keep the aquarium filled near to the top. If you have a turtle with any hint of ninja escaping abilities, you're pretty much on your own on figuring out a way to cover the remaining space, as no off-the-store-shelf product will cover such an odd amount of leftover space. I was lucky that my filter and aquarium light nicely covered the remaining free space in my 20g tank.
Review: World’s greatest aquatic pet turtle product!!! - Finally, a company that has made the world’s greatest aquatic pet turtle product!!! It shows how scientifically advanced we have become, only you have to supply the lamp. My turtles were at first shy of it, but it only took a matter of minutes and less than a day for them to start taking turns climbing up into the enclosed platform to bask. The clear top is movable with ridges to clamp several lamps, from both sides, and a metal grid door on top that can open if you need to insert food, etc. into it. Everything is made super easy. I have five mapping turtles. The size is great for them and the topper fits on my 37 gallons, near perfectly. Make sure you measure the size before purchasing. The only natural setback is that the turtles can get spooked from the clear plastic and hop quickly back into the water. I suggest covering the clear plastic with plants or other décor to provide them with a more hidden environment and hence they are less likely to get spooked, but also less visible when they are in there. Overall, it is a great product for aquatic turtles!!!

### ⭐⭐⭐⭐⭐ My Red Eared Slider LOVES this!
*by A***S on September 9, 2020*

My favorite Turt in the world Jade lovessss this thing more than she does me! She hangs out on it ALL DAY. She sleeps on it every night. She uses it to escape her New World cichlids sisters when they follow her and expect her out of curiosity too much when she swims 😂. This thing is so sturdy along with the top she’s 3 years old and 5 1/2 inches & it’s safe enough to hold her up while she climbs up feeling curious herself and watches me. & it doesn’t move all I hear are her scratches while she peeks her head up and even then no scratches! She scratches being curious sometimes tryna see what’s going on outside of her world and this thing is so durable. I’m upgrading her to a new 90 gallon tank soon when I finally move into my house and out of this apartment definitely will have to get her a custom made Basking area. She will truly miss this and i hope she doesn’t go on strike or get angry with me. I know she loves it so very much. For the people being scared to fill up their tank FILL IT UP!!! trust me these sliders and diamondback terrapins love to swim! It’s their life along with getting daily tans. Trust me u will see a change in personality and mood when your turtles are truly happy. As to those with any manufacturer issues your problem not having a easy setup or set up wrong and haven’t discovered it yet. As anyone would putting together something new, just TAKE YOUR TIME. Breathe, don’t get frustrated really take your time read the instructions, look at the pictures in the manual, watch the YouTube videos on how to install the Penn Plex Turtle Topper. It’s really simple. I had a hard time too at first . Take your time because of course with mishandling anything can break. & u don’t want that. So take it easy on yourself. Enjoy putting it together for your pet. And enjoy watching them love what u fought so hard to put together for them. Shipping came during the beginning of COVID-19 in NYC so I had to wait but it wasn’t a ridiculous wait. It came as expected in great condition, very well packed. Jade loves it, so thank you so much.
