Kryptonite Stronghold Anchor, Permanent Indoor Outdoor Bike Locking Point, Heavy Duty Anti-Theft Ground Anchor for Bicycles E-Bikes Scooters, 6.10 lb Steel Security Mount

Positives: Very solid product. Quality build. This will not be the weakest link in my security. I used an old electric drill with hammer action and the bits help up perfectly. My concrete was poured 3 years ago with no visible cracks. Negatives: Takes some elbow to install. SUGGESTIONS: 1 Consider your location carefully 2 Allow plenty of time for install. It took me an hour to install. I could do it a second time in probably 20 minutes. 3 Following the directions exacty as indicated ... with possibly one exception .... You will drill three holes total into the concrete. The directions state to use the big bit for the first hole and then use the smaller bit first for a pilot hole and for accruacy before using the larger bit for the other two holes. I would suggest using the smaller bit and drilling a pilot hole for your first hole too. This will help drill the hole perpendicular to the floor and will reduce spalding or busting out some of the concrete if you try to drill the first hole with the larger bit only. 4 Do not attempt to drill all three pilot holes at once. Follow the directions. Drill one hole and fit one anchor. Then do the second and then the third. Do them one at a time. This will asure accurate placement of the achors. 5 Drill each hole perpendicular to the floor taking the time to check as you go. This will prevent trying to round out the hole if you get started wrong. A good straight hole will help the sleeve to fit in nice and tight for added security. 6 Use a shop vac as you drill to remove the dust. Drill a little, stop, use the vac and then drill some more checking that your drilling perpendicular to the floor as you go. The three achors will then fit nicely in your holes. This is not rocket surgery as my friend says. You are drilling three holes and installing three anchors. My installation went very well. Allow yourself some time, follow the directions and your install will go very well.

I was quite overwhelmed upon receiving this product. My first impressions: it was big, heavy and felt like it was over engineered. There is nothing flimsy at all with the entire construction, even the plastic cap was thick, so thick that a heavy vehicle can easily drive over it without being damaged. I did have some doubts on how the installation will proceed after reading some of the negative reviews here. So I decided to read and understand the instruction manual. We set the mounting plate on the concrete pavement and drilled a hole with the pilot drill on the first marked hole on the plate. Once the drill was an inch into the material, we removed the plate and drilled to the length of the anchors. We vacuumed all the dust out then proceeded to drill with the final moly. We then carefully vacuumed all of the dust out the pushed the anchors into the hole, placed the mounting plate and screwed the bolt tight. Note that if the hole is carefully cleaned of all the drilling material, you don’t have to hammer the anchors, you can simply work them in using your fingers. We then proceeded to drill into hole #2 of the mounting plate with the pilot drill and repeated the procedure above, and the same went for hole #3. After all the anchors were placed we tightened the bolts and the plate gripped the concrete securely. There was no play or wiggle at all that can be perceived. The supplied bolt head seals/caps were hammered in place that made the installation permanent. Finally the plastic cover was screwed in place and what you see is the product successfully installed. Many folks advised using a hammer drill. We used a regular corded Dewalt drill and took our time drilling and vacuuming the dust and it worked very well. The job was surprisingly easy and straightforward. Best of all we now something to secure our bicycles and am confident that it will perform as designed. Final impressions: excellent product, easy to follow instructions and all materials needed were supplied for a successful installation.

Excelente fácil para instalar y en combinación con kryptonite cadena y candado puedo dormir bien sabiendo mi moto tiene buen protección aunque nada es 100% perfecto en contra robo.

Das Kryptonite Stronghold eignet sich sehr gut für Roller, Motorräder oder Fahrräder. Seine robuste Konstruktion und einfache Installation machen es zu einem verlässlichen Bodenanker. Die Vielseitigkeit ermöglicht eine flexible Anbringung an verschiedenen Orten. (Im Boden, an einer dicken Betonwand, etc) Ich finde es super, dass der Anker sogar mit den notwendigen Bohrköpfen kommt (1x kleinerer Primer-Bohrkopf zum Vorbohren, 1x dicker 16mm Bohrkopf für die Metalldübel). Die mitgelieferten Sechskantschlüssel sind zu kurz. Der Anker ist damit nicht montierbar, man bekommt die Schrauben nicht zugezogen. Idealerweise hat man ein Rohr um eine Hebelwirkung zu erzielen, oder eine Impact Drill mit einem guten Hex Bit.

This anchor really works and it comes with all the installation bits needed thank.

ハンマードリルがないと取り付けられませんがその分かなり期待できます。簡単には引き抜けないでしょう。穴を空ける際は十分に注意して位置を決めないと失敗するかもしれません。取り付ける前に穴の位置を見直して、ダメなら穴を広げて余った部分にセメントをいれるなどするといいと思います。たとえ全部のボルトが入ってなくても抜くのは困難だと思います。

Più grosso di quanto possa sembrare in foto. Realizzazione ottima, molto curata. La sensazione è di estrema robustezza. Il kit comprende anche le punte da trapano e le chiavi a brugola necessarie per il montaggio. Un consiglio: prima di inserire le viti (già assemblate con i relativi tasselli metallici) assicuratevi che i fori praticati con il trapano (ATTENZIONE: di potenza sufficiente per una punta da muro di 16mm) siano sufficientemente ampi ovvero che la punta dopo aver forato abbia un minimo agio. In caso contrario, se il tassello sforza un po', rischiereste di rovinare il fragile assemblaggio dei tasselli stessi, pregiudicando i successivi tentativi di inserimento nel foro. Spero di essere stato sufficientemente chiaro. Consigliatissimo per box e cantine a protezione di bici troppo poco difese dalle sole serrature degli accessi.
